Ritchies CEO Michele Kernahan Steps Down as Scott Thorne Takes Charge With Immediate Effect

One of New Zealand’s largest passenger transport companies has changed chief executives without a transition period, as Ritchies enters another critical phase in its post-family-ownership era.

10 August 2026 | Kiwi Coaches Industry News & Analysis

Ritchies Transport has made an immediate change at the top of its business, with chief executive Michele Kernahan stepping down and Scott Thorne appointed Chief Executive effective immediately.

An internal communication was sent to Ritchies employees on Monday, 10 August, from Ritchies Board Chair John Williamson and the company’s Board of Directors.

The notice describes the move as a “leadership transition” and says Kernahan has decided that the time is right to step away after approximately four years leading the company.

There is no suggestion in the communication that Kernahan has been dismissed.

But equally notably, there is no announced notice period, interim chief executive, recruitment process or extended handover.

Instead, Scott Thorne — already one of the senior figures inside the business — becomes chief executive immediately.

That makes the change one of the most significant developments in New Zealand passenger transport this year.

It comes as Ritchies is simultaneously dealing with one of the largest public-transport mobilisation programmes ever undertaken in New Zealand, a rapid transition toward electric fleet, the integration of multiple acquired businesses, changing regional contract positions, and an ownership story which has remained unresolved publicly since reports emerged last year that private-equity owner KKR was considering selling the company.

As of Monday evening, Ritchies' public website was still directing visitors to a chief executive message from Kernahan.

What Ritchies has told its employees

The notice is attributed to John Williamson, Board Chair, and the Board of Directors of Ritchies.

It says Kernahan is leaving after overseeing what the board describes as a period of growth and transformation.

The board cites acquisitions, tender wins, internal process changes and the beginning of large-scale depot and fleet electrification among the developments during her tenure.

It then states:

Scott Thorne has been appointed Chief Executive, effective immediately.

The communication says Thorne joined Ritchies in 2023 as Director of Assets and Strategy and has led growth, fleet and depot programmes, including mobilisation of new service contracts.

Employees are told there is a “smooth, well-managed transition underway” and that it is business as usual.

What the announcement does not explain is potentially as interesting as what it does.

It does not set out when Kernahan first advised the board she intended to leave.

It does not disclose whether a formal succession process had been underway.

It does not indicate whether she will remain available to the business during a handover.

It does not discuss the ownership or sale position of Ritchies.

And it does not identify any single event behind the timing of the decision.

Those omissions should not be interpreted as evidence of a dispute or crisis. They do, however, make the immediacy of the transition notable.

For a company of Ritchies' size — its current website says more than 3,000 employees, a fleet exceeding 2,200 vehicles and more than 100,000 passenger movements a day — changing chief executive without an announced transition period is significant.

Michele Kernahan: brought in to transform the post-family Ritchies

Kernahan was not a traditional bus-industry appointment.

She was recruited into Ritchies in April 2022, shortly after KKR's acquisition of the historically family-owned company had been completed.

Her background was largely in corporate management, construction, manufacturing and freight rather than passenger transport.

She spent around two decades at Fletcher Building and its associated businesses, including periods as chief executive of Building Products and chief executive of Fletcher Construction. Before joining Ritchies, she had also served as chief executive of refrigerated transport and logistics company Hall's Group.

That background fitted the task facing Ritchies at the time.

The business that KKR had bought was enormous by New Zealand standards, but it had been assembled over generations under a family-business model.

The new owner was an international investment firm.

Kernahan's appointment was explicitly presented at the time as part of a transformation and growth programme.

Recruitment firm Johnson Partners, which assisted with the appointment, described the mandate as developing and implementing a sustainable growth strategy and change programme spanning technology, innovation and diversification.

She replaced Andrew Ritchie as chief executive.

That meant that in little more than a year Ritchies had moved from generations of family ownership and management to offshore institutional ownership with an externally recruited professional chief executive.

It was a fundamental change in what Ritchies was.

From Temuka family company to private-equity infrastructure asset

Ritchies traces its origins to Temuka in 1935, when Johnny and Marie Ritchie began the operation that would eventually become one of the biggest passenger transport businesses in the country.

For decades the company expanded organically and through acquisitions, ultimately developing operations extending across urban public transport, school transport, tourism, charter, intercity services and regional transport.

By the time KKR agreed to acquire Ritchies in 2021, the company reported more than 1,600 vehicles, approximately 1,800 employees and 42 depots.

The purchase price was never formally disclosed by the parties.

Contemporary reporting, however, put the transaction value at around NZ$500 million.

The transaction was notable beyond the bus industry.

It was KKR's first infrastructure investment in New Zealand.

Infrastructure funds were attracted to bus companies in part because urban public transport can provide relatively predictable long-duration revenue backed by government and council contracts.

But a bus company is also an extremely capital-intensive asset.

Vehicles wear out.

Depots need investment.

Technology changes.

Staff costs are substantial.

And the transition from diesel to electric buses has pushed significant new capital expenditure into an industry already operating on tight contract economics.

Those two characteristics — defensive contracted revenue and heavy capital requirements — remain central to understanding Ritchies today.

The acquisition strategy accelerated

Under KKR ownership, Ritchies did not simply maintain its existing footprint.

It continued consolidating the market.

In 2024, the New Zealand Herald reported that Ritchies had acquired three family-owned operators — Greenline Motors, Pearson's Coachlines and Leabourn Passenger Service — for a combined sum exceeding $57.3 million.

The purchases were another example of the structural change occurring across New Zealand passenger transport.

Businesses that had often been family-owned for generations were increasingly being absorbed into much larger transport groups backed either by institutional capital or substantial national operators.

Then came another important Auckland acquisition.

In February 2025, Ritchies announced it was acquiring Pavlovich Coachlines at the same time Auckland Transport awarded Ritchies what AT described as the largest tendered bus-services contract in New Zealand history.

The contract changed the scale of the company again.

The $1.068 billion Auckland contract

Auckland Transport awarded Ritchies a nine-year contract worth $1.068 billion covering five contract units across South and West Auckland.

It included the introduction of 175 electric buses.

AT said the package was the largest tendered bus-services contract in New Zealand.

Two new Ritchies depots opened in Māngere later in 2025, with the sites supporting more than 250 drivers and operational staff and initially accommodating 102 electric buses.

This programme matters enormously when considering today's leadership change.

Ritchies is not simply operating a mature network of inherited contracts.

It is in the middle of an unusually large fleet, depot, staffing and service transition.

Its own website currently says its fleet has expanded to more than 2,200 vehicles and that it operates 210 electric buses in Auckland, with 11 sites expected to have EV charging infrastructure by the end of this year.

That is a materially different organisation from the 1,600-vehicle Ritchies acquired by KKR.

But growth has not meant a year without problems.

Dunedin contract losses and workforce uncertainty

There has also been pressure at contract level.

In February, the Otago Daily Times reported uncertainty among Ritchies drivers in Dunedin after the company lost more than half of its Orbus routes when Go Bus became the lead contractor.

A driver told the newspaper that potentially dozens of Ritchies staff could be affected.

Ritchies declined to discuss the workforce implications, citing the commercial nature of the arrangement with the Otago Regional Council.

Large public-transport companies routinely gain and lose contracts.

That is the nature of a tendered industry.

But losing major contracts while simultaneously mobilising very large new ones illustrates one of the central management challenges of modern bus operations: workforce, vehicles and depots constantly have to be redistributed around a procurement cycle determined largely by public agencies.

Ritchies is winning contracts — but competitors are winning too

The wider Auckland procurement market has also demonstrated that Ritchies' 2025 billion-dollar win did not give it a permanent advantage.

In 2026, Auckland Transport awarded Kinetic four major contract units worth a combined $755 million.

Those contracts replaced ten smaller existing contract units previously held variously by Kinetic, Ritchies and Howick and Eastern by Transdev.

This is important context.

Ritchies is large.

But so are some of the companies it competes against.

The New Zealand public-transport market is increasingly becoming a contest between large groups capable of financing fleets, building electric depots, managing hundreds of drivers and carrying the financial exposure involved in long-duration government contracts.

That environment helps explain why ownership, capital structure and executive leadership matter far beyond the executive offices at Swanson Road.

The sale story hanging over Ritchies

The largest unanswered strategic question surrounding Ritchies has for almost a year been ownership.

In August 2025, Australia's DataRoom reported that KKR was seeking investment-bank advice on strategic options for Ritchies, including a possible sale.

The report said KKR had paid about NZ$500 million for the business and suggested the fund could be a motivated seller.

By November, reporting had become more specific.

Macquarie Capital was said to have been appointed to run a Ritchies sale process, with the business expected to be taken to market during 2026.

That naturally attracted attention from across the Australasian transport industry.

Kelsian, the Australian-listed transport group, was subsequently among the names discussed in market reporting as a logical potential participant.

But there has been no publicly announced buyer or completed transaction.

And more recent reporting suggests the process may no longer be proceeding on its original timetable.

In July, DataRoom reported that sources close to KKR were playing down a near-term sale and that KKR was not then looking at an immediate monetisation.

The same reporting pointed to thin buyer appetite for large bus assets and the significant capital expenditure still required across the sector.

That is a materially different picture from November's expectation that Ritchies would shortly be put on the market.

It would therefore be inaccurate to say publicly that Ritchies has received “no offers”.

Private sale processes are, by definition, private.

There may have been approaches, expressions of interest or discussions which have never entered the public domain.

What can be said is simpler:

No buyer has been publicly announced, no completed sale has been announced, and recent reporting suggests KKR has cooled the immediate sale process.

That makes tonight's leadership change still more interesting.

There is no evidence in the staff announcement connecting Kernahan's departure with the ownership process.

But any future buyer of Ritchies will now be assessing a company under a different chief executive from the one who oversaw most of KKR's transformation programme.

Why selling a bus company is harder than it looks

The Ritchies story also provides a useful window into a larger industry problem.

From a financial perspective, public-transport operations can look extremely attractive.

A successful operator may hold contracts lasting eight, nine, ten or more years.

The counterparty may effectively be a council or government agency.

Passenger demand can fluctuate without necessarily eliminating the contracted revenue stream.

That is the kind of relatively defensive cash flow infrastructure investors like.

But buses are not passive infrastructure.

They require constant operating expenditure and periodic capital replacement.

Electric buses increase the scale of the initial investment.

A depot can require new electrical connections, charging systems, civil works, software and grid capacity.

Meanwhile, hundreds or thousands of drivers must still be recruited, trained and retained.

Winning an enormous contract therefore produces both revenue and obligation.

The nine-year Auckland contract illustrates this perfectly.

Ritchies secured more than $1 billion of contracted revenue.

It also committed itself to 175 new electric buses and substantial supporting infrastructure.

The value of the contract cannot meaningfully be assessed without considering both sides of that equation.

It is one reason leadership centred on fleet, assets, mobilisation and commercial discipline becomes particularly important.

And that brings the story back to Scott Thorne.

Who is Scott Thorne?

Thorne is not a new arrival to the New Zealand bus industry.

His career predates his time at Ritchies by many years.

Public records and reporting show him occupying senior strategy and commercial positions at NZ Bus, including General Manager Strategy and later Chief Commercial Officer.

He was involved with public-transport contracting, network change, electric buses and commercial negotiations.

In 2019, for example, Thorne was the NZ Bus executive publicly commenting during the company's highly contentious Auckland industrial dispute with drivers and unions.

He also had involvement in NZ Bus's Tauranga operation and the early introduction of electric buses there.

Companies records show William Scott Thorne serving as a director across a range of NZ Bus entities, including NZ Bus Limited, North City Bus Limited, Wellington City Transport Limited and related companies.

He therefore brings substantial experience not simply in buses, but in the more specialised world of contracted urban public transport.

That distinction matters.

Charter and tourism operators sell transport directly to customers.

Urban operators increasingly sell capability to public agencies through complex long-duration contracts.

Fleet models, bid pricing, depot infrastructure, service performance, industrial relations, asset utilisation and contract mobilisation become central to the economics.

Thorne's career has been heavily exposed to that environment.

Thorne's role in the modern Ritchies

Thorne joined Ritchies in 2023.

His title has variously been publicly presented around assets, transformation and strategy, but the consistent theme has been responsibility close to the capital-intensive side of the business.

Ritchies currently identifies him as Director of Assets & Strategy and as its representative on the board of the Bus and Coach Association.

His own public activity has repeatedly focused on fleet investment, electric depots, contract mobilisation and Ritchies' large Auckland expansion.

That makes him a logical internal successor if the board's immediate priority is execution.

It also makes his appointment strategically different from Kernahan's appointment in 2022.

Kernahan arrived as an external transformation chief executive after a change in ownership.

Thorne takes over after much of that structural transformation has already occurred.

His challenge is increasingly one of delivery.

John Williamson: the chairman behind the transition

The other major player in today's announcement is John Williamson, the Ritchies Board Chair.

Williamson has considerable experience governing privately owned, listed and private-equity-backed companies.

He previously served as group chief executive of ACG Education, group managing director of Hellaby Holdings and held senior Fletcher Building positions.

He is also Chair of the Guardians of New Zealand Superannuation, the Crown entity governing the NZ Super Fund.

The NZ Super Fund's official biography identifies him as Chair of Ritchies Transport Holdings.

Williamson was appointed to the Ritchies Transport Holdings board in September 2022, only months after Kernahan became chief executive.

That places both figures firmly within the KKR-era governance structure rather than the former family management regime.

The language of today's staff communication is accordingly conventional corporate-governance language: continuity, orderly transition, confidence in the successor and business as usual.

The more difficult questions — particularly around the sale process and the precise circumstances surrounding the timing — remain unanswered publicly.

And what happened to Andrew Ritchie?

One of the more unusual elements of the modern Ritchies story is that former owner and chief executive Andrew Ritchie has remained highly active in the wider transport industry after leaving the company bearing his family name.

Andrew represented the next generation of the Ritchie family in the business and spent decades in passenger transport.

When the KKR acquisition was announced in 2021, the plan was for Andrew to become chief executive while Glenn Ritchie retired.

KKR's announcement specifically described Andrew's elevation as part of the post-acquisition structure.

His period as chief executive proved brief.

In April 2022, Kernahan was appointed CEO and Ritchies said Andrew would continue working on several strategic projects with the board and new chief executive.

Companies Office-linked records later show his directorship of Ritchies Transport Holdings ending in 2022.

But he did not leave transport.

NHR Group

Ritchie became a director and shareholder of NHR Group, a New Zealand truck, van and bus rental business.

In 2024, NHR announced a major franchise relationship with Hertz and Thrifty for truck and van rental in New Zealand, with Andrew Ritchie publicly commenting as a director of NHR Group.

That put him back into a sizeable transport and vehicle business — just outside the company carrying his surname.

Property, investment and tourism interests

Companies records also show Andrew Ritchie building a much broader portfolio after leaving Ritchies, with interests spanning investment, finance, property and other ventures.

One more visible project emerged in 2025.

The Otago Daily Times reported that Ritchie and business partner Adam Stewart had acquired Dunedin's former Aaron Lodge site to redevelop it as Stayhub Holiday Park Dunedin, with a multimillion-dollar refurbishment planned.

That puts the former Ritchies executive back into tourism as well as transport and vehicle rental.

But the most consequential role came this year.

Andrew Ritchie is now Chair of Auckland Transport

In February 2026, Auckland Council appointed Andrew Ritchie as chair of the interim Auckland Transport board overseeing one of the most significant governance restructures in the organisation's history.

The appointment became operational through the transition structure in May.

Auckland Council described him as having more than 30 years' leadership experience across transport and tourism, including his former roles as Ritchies Director of Operations and CEO and as president of the Bus and Coach Association.

He is now chairing the public body responsible for overseeing Auckland's public-transport operations during its governance transition.

That same agency is also one of Ritchies Transport's most important contracting counterparties.

That fact does not suggest wrongdoing.

Nor should any conflict be presumed merely because of prior industry employment.

But it illustrates how interconnected New Zealand's relatively small senior transport community remains.

The former Ritchies chief executive is now chairing Auckland Transport.

His successor Michele Kernahan has now departed Ritchies.

And Scott Thorne, another executive with decades inside the country's largest urban bus operations, has taken over.

A company at a very different point from 2022

When Kernahan became chief executive in April 2022, Ritchies had just changed ownership.

Her brief was effectively to move the company from an old family-owned transport structure into a modern institutionally owned infrastructure business.

Four years later, that transformation is substantially advanced.

Ritchies is bigger.

Its own figures now put its fleet above 2,200 vehicles and workforce above 3,000 people.

It has acquired regional competitors.

It has absorbed Pavlovich.

It has won the largest tendered bus contract in New Zealand history.

It is deploying hundreds of electric vehicles.

It has built and electrified depots.

It has considerably more exposure to massive long-duration public transport contracts.

But it also has more capital tied up in the business, greater execution risk, increased dependence on institutional procurement and a private-equity owner whose ultimate exit remains unresolved.

That is the company Scott Thorne inherits tonight.

What does this mean for the wider New Zealand bus industry?

The immediate effect for passengers should be limited.

Ritchies says there will be no change to day-to-day operations, teams or existing customer relationships.

That is entirely plausible.

A chief executive does not drive Monday morning's scheduled bus.

The more important implications are strategic.

1. Ritchies may become even more focused on contracted public transport

Thorne's professional background is overwhelmingly relevant to large-scale urban public transport.

He understands tendering, network mobilisation, capital investment, fleet economics and public-sector contracting.

That makes a further emphasis on contracted urban transport one possible direction.

It would continue a trend already well underway under Kernahan.

2. Capital discipline may become more important

Ritchies' current expansion requires enormous investment.

Electric buses, depot electrification and contract mobilisation consume capital before the full economic returns from a contract are realised.

That becomes particularly important when the shareholder is an infrastructure fund which will ultimately need to realise its investment.

An executive with an assets-and-strategy background may be particularly valuable at that stage.

That is analysis rather than a stated Ritchies strategy.

3. The sale question will become harder to ignore

Any serious potential buyer of Ritchies would want confidence in management continuity.

Changing chief executive during an ownership review does not necessarily damage a transaction.

In some circumstances a buyer or seller may prefer a different management structure.

But until KKR states clearly what it intends to do with Ritchies, each major strategic move will inevitably be viewed through the ownership lens.

The question has changed from:

Who might buy Ritchies?

to perhaps:

Does KKR still intend to sell Ritchies at all — and if so, when?

4. Consolidation across the industry is not over

Ritchies is only one part of a much bigger restructuring of passenger transport.

Kinetic has grown substantially.

Tranzit remains a major independent New Zealand operator.

Ritchies itself has bought multiple smaller companies.

Public agencies are bundling contracts into larger packages requiring greater financial capability.

That naturally favours scale.

The risk is that fewer businesses may eventually possess the capital and operational resources necessary to compete for major urban packages.

The counterargument is that large operators can fund technology, safety systems, new depots and zero-emission fleets that smaller businesses may struggle to finance.

Both are valid considerations.

The end result is a bus industry increasingly shaped as much by finance and infrastructure investment as by buses themselves.

Questions Ritchies still needs to answer

The staff announcement resolves one question unequivocally.

Scott Thorne is now Chief Executive of Ritchies Transport.

It leaves several others unanswered.

When did Michele Kernahan first advise the board of her decision?

Why was the change effective immediately rather than following an announced transition?

Will Kernahan retain any role during a handover period?

Was an internal succession plan already in place?

Does the change have any relationship to KKR's previous exploration of a sale?

Is Macquarie still formally engaged on the Ritchies mandate?

Has KKR abandoned, postponed or merely slowed its exit process?

And does the appointment of an asset and strategy executive indicate a change in the company's commercial priorities?

There may be straightforward answers to all of them.

Until they are provided, speculation should not be presented as fact.

The end of the Kernahan era

Michele Kernahan leaves behind a Ritchies substantially different from the company she inherited in 2022.

The family era was already ending when she arrived.

Under her tenure the institutionally owned version of Ritchies became firmly established: larger contracts, more acquisitions, larger fleets, more centralised corporate structures and rapid electrification.

She also leaves after a year containing contract losses, safety-related headlines, an adverse Employment Relations Authority decision and continuing uncertainty around KKR's eventual ownership exit.

Those facts coexist.

Neither the achievements nor the problems establish why she has chosen to leave now.

The only definitive explanation currently available is the one provided by the Ritchies board: Kernahan decided that, after four years leading the organisation, the time was right to step away.

Scott Thorne now takes responsibility.

And unlike the Ritchies of previous generations, where ownership, family and management were closely intertwined, today's organisation answers ultimately to one of the world's biggest investment firms.

That makes this more than a change of name on an office door.

For Ritchies, the next phase is about proving that the scale assembled during the Kernahan years can be operated consistently, financed sustainably and converted into long-term value.

For KKR, the bigger unresolved question remains what it ultimately intends to do with the business.

And for the wider New Zealand passenger-transport sector, tonight's change removes one of its most prominent chief executives and puts another highly experienced industry insider into control of one of the country's largest operators at a particularly consequential moment.

This story is developing.
