Profiles

Stephen Williamson – Partner, Chartered Accountant, JP, B.Com, CA

Stephen moved to Pukekohe in 1986 from a Charted Accountant Practice where he specialised in auditing some of New Zealand’s major Public Companies. A fast growing International Partnership Touche Ross was established. In 1990, a series of international mergers occurred and the opportunity was taken to make the Pukekohe office a stand alone operation.

In 1994 Stephen decided it was time to form a new independent practice for the benefit of the local staff and clients. We are proud that we have a wide diversity of clients, from farming to SME’s and community based organisations.

Outside his professional responsibilities, Stephen’s passion is football (the round ball version), where he participated actively on a weekly basis until 2023 and was involved in Local, National and International administration of the game. Stephen enjoys his other passion of trout fishing at Lake Rotoiti, Rotorua, where results are often mixed.

In October 2012, Stephen was appointed a Justice Of the Peace of New Zealand by the Governor General and continues this valuable Community Service on a regular basis for clients and the community.
