Senior Associate


Geoff Rashbrooke qualified as a Fellow of the Institute of Actuaries in 1979. He has worked for insurance companies and actuarial consultancies, and as a consultant on his own account. In the late 80’s he was in the NZ Government Actuary’s Office, and returned in 1997 to be Government Actuary up until the end of 2001. In that role Geoff was responsible for the regulation of NZ retirement savings schemes, as well as advising on life and general insurance regulatory matters, and providing advice on life insurance taxation to the Inland Revenue.

Geoff’s consulting work has included advice on earthquake insurance for the Earthquake Commission, acting for members of the Southern Cross Health Association, and two months advising the government of Armenia on regulation of life insurance.

During his time as Government Actuary Geoff developed an interest in retirement income and savings policy, and from 2004 to 2009 was a specialist in that area as a Principal Analyst in the Ministry of Social Development. He gave advice for the Ministry on KiwiSaver development, and was its representative on the KiwiSaver Evaluation Steering Group.
