Press Release
Grant Thornton Advisors expands multinational platform by welcoming Grant Thornton New Zealand
03 Nov 2025
CHICAGO and AUCKLAND, 3 November 2025 – Grant Thornton Advisors LLC (Grant Thornton Advisors) today announced that its multinational platform is growing to include Grant Thornton New Zealand – a move that extends the platform’s reach across 20 time zones into the Asia Pacific region.
The New Zealand firm is a recognised leader in its region, with US$40+ million in annual revenue and a team of more than 300 dedicated professionals. It is known for its strength in key markets and its reputation for delivering leading audit, tax and advisory services.
Grant Thornton Advisors launched its platform earlier this year with the support of an investor group led by New Mountain Capital — and is already bringing more than a dozen high-performing firms across the Americas, Europe and the Middle East into an integrated advisory and tax practice, complemented by independent audit practices.
The platform currently includes Grant Thornton firms in the US, Ireland, France, the United Arab Emirates, the Netherlands, the Channel Islands and the Cayman Islands. Additionally, it previously announced transactions with Grant Thornton firms in Spain, Switzerland, Liechtenstein, Belgium and Luxembourg, which it anticipates closing in the coming weeks. Further, it has added top firms serving strategic markets and industries, including Auxis, a pioneer in outsourcing and business modernisation — and Stax, a specialist in commercial due diligence and value creation.
“Modern businesses demand seamless service and consistent quality — whether they’re operating in New York, Auckland or locations in between,” said Jim Peko, CEO of Grant Thornton Advisors LLC. “By welcoming Grant Thornton New Zealand to our platform, we’re expanding our multinational reach into a vital region with a firm that shares our ambition and values. Together, we’re building a truly borderless one-of-a-kind platform that delivers exceptional outcomes across industries and geographies.”
Russell Moore, CEO of Grant Thornton New Zealand says: “This is an extremely exciting time for Grant Thornton New Zealand – for our business, our people and for the clients we work alongside. As our market continues to evolve, businesses are looking for smarter solutions, deeper expertise and global connectivity. By joining Grant Thornton Advisors, we can deliver all three — bringing world-class technology, insight and capital to help our clients grow with confidence, both in New Zealand and beyond.”
The transaction is expected to close later this year.
The expanded platform will continue to be part of the Grant Thornton International Limited network, which comprises member firms in more than 150 markets worldwide.
Simpson Thacher & Bartlett LLP and MinterEllisonRuddWatts provided transaction services to Grant Thornton Advisors. Major advisors to Grant Thornton New Zealand included Tompkins Wake.
