Lance O'Sullivan, who quit his job with a Maori health clinic in June, is to open his own general practice in Kaitaia.
Dr O'Sullivan resigned from Te Hauora (Te Hiku o Te Ika) after repeated warnings not to make house-calls or treat people who could not pay.
But he says having his own practice will give him the flexibility to help patients, especially Maori, as and when they need him.
Dr O'Sullivan, who led A campaign against rheumatic fever in Northland, says he will also continue to speak out about poverty and poor housing in his community.
As long as those conditions persist, he says Maori children will suffer poor health compared to the general population.
Dr O'Sullivan says he expects to open his practice before Christmas and hopes other like-minded doctors might eventually join him.
