Mr Porter is well known in the Far North as a vocal advocate for Maori rights and the environment. He has been one of the main players in the protests against Norwegian firm Statoil's plans to explore for oil off the west coast. He also develops affordable housing on Maori land.
He contested the Far North mayoralty in the 2013 local elections, placing fifth of seven candidates with 1014 votes.

National's nominations close at noon today with a shortlist of the top five hopefuls to be released on Saturday. So far Maungaturoto farmer Grant McCallum and Okaihau farmer/fraud investigator Matt King have publicly put their hands up for the job. Both ran for selection when National last sought a new candidate in 2011.
Announcing his nomination yesterday Mr King said, if selected, he would bring a good balance of life experience to the job. He was a farmer and family man who had worked 14 years as a police detective and owned several businesses, most recently Mid North Honda.
He said he could relate to people on all levels and would bring a "practical, down-to-earth common-sense attitude" to the role.
The Greens are due to decide today whether to contest the byelection. If they do Kerikeri-based list MP David Clendon is likely to be their candidate.
NZ First leader Winston Peters is believed to be considering a tilt at the seat.
