Business Support Manager - Carolyn Stiles

Carolyn's role at Cholmondeley is really varied and, as the name suggests, she supports the organisation but in lots of different ways. On any given day you could find Carolyn looking at our finances, debating fundraising campaigns with the Sustainability Team, helping with recruitment or making sure the building is the right temperature for all the tamariki and staff – each day is different and very interesting and she thoroughly enjoys it.

Carolyn is from the UK (West Wales) where she spent about 11 years working for a bank and then 11 years working for one the UK’s biggest insurance companies. After taking some time out to migrate to New Zealand and have a baby, she then stepped into a general management role at SportsMed based in Christchurch. Carolyn also has a number of year’s governance experience having sat on Boards for organisations both in the UK and New Zealand.

"I’ve found a great philosophy throughout my life is 'Always treat others as you would want to be treated yourself'. So whether you are communicating with children, whānāu, community, staff or whoever - just doing all those things that you would want from them usually makes for a winning combination."
