Greg is in his first term as the Member of Parliament for Maungakiekie. He serves on the Māori Affairs Committee and is Deputy Chair of the Petitions Committee. In March 2024, the members’ bill in his name, the Crimes (Increased Penalties for Slavery Offences) Amendment Bill, was drawn from the ballot, aiming to strengthen New Zealand’s response to human trafficking by increasing penalties for domestic trafficking offences to match those for international trafficking.

Born in Masterton, Greg attended Wairarapa College and gained a Bachelor of Commerce from Victoria University. A Chartered Accountant, he began his career in London finance and is a student of te reo Māori.

In 1998, Greg left accountancy to address family fragmentation, leading Parenting With Confidence (now Parenting Place) through significant growth. He later co-founded The Maxim Institute and became Chief Executive. With 25 years’ experience in the charitable sector, Greg has helped build enduring community institutions and was appointed CEO of The Parenting Place in 2015. He has lived in Maungakiekie since 1998, where he and his wife Kirstin have raised their five children.
