Waitakere Mayor Bob Harvey wants to see iwi co-management of volcanic cones in Auckland extended to Centennial Park, which makes up a significant part of the Waitakere ranges.
Treaty Negotiations Minister Chris Finlayson has asked Auckland Regional Council, which owns the park, to consider the idea.
Under the current proposal, 11 cones would be jointly managed by the collective iwi representatives and the new Auckland Council.
Mr Harvey told Waatea News that Waitakere City has worked closely with Te Kawerau-a-Maki in managing its part of the ranges and he sees no reason the partnership should not continue with the super-city.
However, ARC chairman Mike Lee opposes the Treaty settlement plan.
Mr Lee says public ownership needs to be protected.
He told Waatea News that Centennial Park was bought in 1941 with public donations to mark the Auckland's centenary.
