Discovering what the little things are for kiritaki, whānau, kaimahi, you really have to genuinely connect with them through every interaction and that’s what Chris holds firm to her approach to mahi.

Prior to this, Chris led the team at ABI Rehabilitation as Chief Executive Officer for four and a half years. With a Master of Business Administration and a Doctorate of Philosophy in Medicine, coupled with her health qualifications and experience, Chris brings a wealth of knowledge and experience that supports advancing healthcare services in Aotearoa.
