Colin Olesen

Hi my name is Colin Olesen and I was born in Otahuhu, Auckland. I am married to Colleen and between us we have 7 children and 18 grandchildren. Together we live on our kiwifruit orchard at 608 No 2 Road, Te Puke, which we also manage. I also manage the family owned kiwifruit orchard across the road from where we live.

After attending Papakura High School, I studied for, then gained, entry to the New Zealand Institute of Chartered Accountants in 1974. With further part time study I was admitted to membership of the Chartered Institute of Secretaries in 1980.

I began my own public accounting practice in Pahiatua in 1975 and moved to Te Puke in 1991.

In 1985 I was appointed a Justice of the Peace for New Zealand.

I joined Rotary in 1992 and was elected Club President in 1995. In 1999 I was awarded a Paul Harris Fellow followed with an appointment to District Governor in 2010. I presently still hold a number of significant roles at District and Club level in Rotary.

I was a member of the Jaycee organisation in the 1970’s and 1980’s. During that time I was a Chapter President and then Deputy Regional Governor.

I have served on local school committees and have also been involved in the establishment of a Residential Home for the Elderly in Pahiatua, where I was Chair of the board for a number of years.

I am on the Board of Trustees, as Chair and Treasurer, of Vincent House Trust in Te Puke, a residential rehabilitation centre. I am also Chair of Directors for Trevelyan Growers Ltd in Te Puke. I am a dedicated Christian and have, over the years, held most positions within Church leadership. I am a member of the Te Puke Baptist Church and am the Chair of Administration.

Outside of work Colleen and I enjoy travel and tramping, I keep a keen eye on the sports results and I also enjoy singing.

Hamish Olesen

Hi, my name is Hamish Olesen. I am married to Mary-Anne and together we have three lively children, Isaac, Eleesha and Joash. We live in Te Puke, close enough for me to walk (and read) my way to work. I was born in the far north but bred in the Manawatu where I attended Mangatainoka primary school and Rathkeale College (Masterton).

After college I went straight to work for my father (Colin) before venturing into tertiary studies. I then completed the first year of Teachers Training College followed by a Bachelor of Business Degree, all while working part or full-time as the study allowed. Overall, I have worked in accounting for 20 years, the past 14 of which have been for the team at Colin Olesen’s.

In 2010 I gained my Chartered Accountant qualification from the New Zealand Institute of Chartered Accountants.

I have a great passion for learning, writing and technology and outside of the office I am actively involved in Church and sport (football and cricket).I also enjoy strategic board games and computer gaming.

Robyn Versteeg

Hi my name is Robyn Versteeg. I am married to Alex and we have two awesome teenagers, Emma and Daniel. We live on a small avocado block and enjoy the lifestyle of country living, but we are still close enough to town. I grew up in Te Puke but left when I was 21 to go to Auckland. This was followed by some time spent in Sydney and then travelling overseas. I returned ‘home’ to Te Puke sixteen years ago to bring up our children in a smaller town.


I joined the team at Colin Olesen’s 8 years ago and have embraced the challenges that and accounting office brings. There have been many technological changes over this time and I have enjoyed the opportunities to learn new skills and to service our client base better.


Outside of work, I enjoy being a Mum and partner to Alex. We enjoy family holidays together and winter is especially busy with both children avid football players.
