About the Team


Tony Thorne

(09) 571 0491


After completing my bachelor of management studies from Waikato University, my first job was as a tax consultant in the tax team at Deloitte which provided me with a strong knowledge of New Zealand tax working with large Corporates. I then worked at a general Chartered Accountancy firm to further my accounting skills and to apply my tax knowledge to small taxpayers.

After gaining that valuable tax and accounting experience, I began Thorne Accounting in 2004 where I was operating as a sole accountant.

Due to growth, my wife Erin (also an accountant!) started work for Thorne Accounting in 2008. On the birth of our second son in 2011, I took on employees to take over Erin's workload. Lesley and Katherine are the fantastic accountants curently working at Thorne Accounting.  Erin has also now returned to Thorne Accounting on a part time basis.

I turned 35 in 2015 so I still consider myself young and enthusiastic so I have plenty of energy to put into the business and clients. The majority of my spare time is spent playing with my young children (now 3 of them). I do manage to find a few hours a week to play soccer for Western Springs in the over 30's division and love to play tennis and go snowboarding when I find the time.

I have worked in accounting since leaving school in 1990.  Starting in a manufacturing business I achieved my finance degree whilst working and then went on to qualify as a Chartered Management Accounting in 1999.

My career in the UK has been in large corporate organisations including the financial services and property sectors.  After arriving in NZ in 2013, I took up a position with Carter Holt Harvey as Group Planning Manager.  These Group roles have given me the opportunity to work with many businesses and people gaining a real understanding of how businesses work.

The arrival of my two sons saw me take an extended period of leave and I returned to work starting my own accounting and payroll training service before joining Thorne Accounting in 2014.

I am passionate about accounting and property, having my own property portfolio and my husband working in the commercial property sector.  I love the lifestyle NZ has to offer and our family spend all our free time making the most of the outdoor life.

I’ve loved numbers for as long as I can remember.  I was still in high school when I was the filing clerk for a small Accounting firm.  This lead on to a role as a trainee accountant within the same firm.

Ten years quickly passed with me completing my Accounting degree and Associated Chartered Accountants qualification and gaining the experience of working alongside business owners and rental investors.  I then moved on to a larger Accounting firm that worked more closely with larger corporate clients.

In 2009, I took up the opportunity to earn a teaching qualification.  In 2012, I returned to the accounting world as a contract accountant with a greater appreciation for the various ways in which people learn and the differences this creates in relaying information to them.

I’m now a hands off investor and believe in looking at the long term big picture when it comes to investing.  I feel this is best achieved by building a diversified portfolio which provides a mixture of positive cashflow returns and increases in capital gain.

I enjoy regular travel around New Zealand in a camper, seeing the wonderful scenery and meeting the friendly locals. This is my passion – long may it last and is my way of achieving a great work life balance.

I have worked at Thorne Accounting on and off since 2008. I am currently back working on a part-time basis and will build this up as our children get older. 

I completed a Bachelor of Management Studies from Waikato University (where I met Tony). My first job was as an auditor for PricewaterhouseCoopers which is where I became a Chartered Accountant and gained great experience working with large manufacturing and retail companies. I then worked at a couple of smaller Chartered Accounting firms and built up my knowledge of accounting for individuals and smaller companies.

My spare time is mostly taken up playing with our 3 children, but I would like to get back into snowboarding once the kids are a bit older.
