Why Māori suffer worse health than other New Zealanders will be investigated by Parliament.
The Māori affairs select committee will hold an inquiry into Māori health inequalities, its chairman and Labour MP Rino Tirikatene confirmed.
The Herald understands the inquiry is likely to include a specific focus on the Government drug-buying agency Pharmac.
However, Tirikatene, MP for Te Tai Tonga, said terms of reference are yet to be agreed: "It may include a focus on Pharmac, but I don't want to get ahead of our committee decision until terms of reference are finalised".
Confirmation of an inquiry follows recent lobbying by advanced breast cancer sufferer Wiki Mulholland and her husband Malcolm Mulholland for access to new generation drugs, and a wider review of the Pharmac model.
