Graeme has recently retired as the New Zealand director of Mercy Ships, an international faith-based organisation that operates hospital ships that sail worldwide and deliver free healthcare to countries with little or no access to safe surgical care.

Graeme began at Mercy Ships in 1983 initially taught the crew's children on board the ships, working his way up to executive leadership roles, going on to help others in 70 different countries worldwide. He sailed on board the ships for 25 years and continued working for the charity at their Penrose offices, where he helped fundraise, recruit volunteers and raise awareness for their work.

Graeme met his wife Sharon aboard Mercy Ships when she worked in the hospitality side. Together they now reside in Onehunga with three children.
