Ngati Rehua Ngatiwai ki Aotea trust board chair Nicola MacDonald said the iwi had kaitiaki responsibilities for Rakitu and knew removing the rats was a vital step to reviving the mauri of the island.
"We are looking forward to working with DOC to restore Rakitu's natural heritage, its wildlife and its forest, for everyone to enjoy."
Auckland Central MP Nikki Kaye said Great Barrier Island was a natural treasure and deserved a higher conservation status than stewardship land.
"A new conservation park on Great Barrier Island would be a great asset for Auckland and would help build the recreation and tourism potential of the island.
"My proposal is for the 15,000 hectares of public conservation land on the island, currently stewardship land, to be designated a new Conservation Park.
"This makes up about 55 per cent of the island and is found in the north and east portions."
The legal effect of the change would result in greater protection for the island's flora and fauna and an increased emphasis on recreation, Ms Kaye said.
"I look forward to talking to residents, and Aucklanders, about my proposal for this new Conservation Park.
"If adopted it would be of similar size to the Hunua and Waitakere Ranges Regional Parks and would be the largest DOC Park in Auckland."
Dr Smith said the conservation park proposal was consistent with the recent Parliamentary Commissioner for the Environment report seeking a review of higher value stewardship land.
"I am instructing DOC to report on the proposal and initiate a process of consultation with the local iwi and the Great Barrier and Auckland communities."
Conservation Week runs from September 8 to September 15.
