The Department of Conservation is again considering the possibility of creating a national park based on Waipoua kauri forest in Northland.
A discussion paper has been issued seeking public submissions on the proposal.
The land under consideration includes the Waipoua Forest and sanctuary and the Maitahi wetland.
DoC says a national park at Waipoua has been talked about for more than a century.
Director general Al Morrison says a previous proposal foundered because of unsettled Treaty claims, which are now complete.
A series of hui and workshops will be held over the next two months and submissions will close on 18 July.
