Te Runanga o Te Rarawa chairman Haami Piripi has said his iwi was not happy with the proposal and felt any consultation would be a "facade". Mr Brown said he understood Mr Piripi's frustrations.
"I think this will be good for Northland in the long term, but in the short term they've got a lot of explaining to do to get everybody on board. We haven't had enough warning to organise ourselves and I don't think the Government has consulted particularly well with our local iwi," Mr Brown said.
He wasn't sure if it would provide the thousands of jobs locally as it was likely that Port Taranaki would still be used as the main port facility for any exploration.
"But if Kaitaia got 2000 or 3000 people earning $100,000 plus it would be a different town. It would be good to have that number of high-paid jobs in the Far North." He felt Kaitaia could be a base to helicopter people and equipment out to any rigs.
Labour list MP and Far North resident Shane Jones said Labour supported the move in principle.
Mr Jones said some Maori may not be happy with the plan due to cultural and spiritual concerns: "There's no guarantee anything will ever happen, but to have investment you have to get the good information before making those (investment) decisions ... Maori unemployment is 15 per cent and it would be 25 per cent or more in some of our kaianga in Tai Tokerau. Let's have a look at this, it might be good for the region."
