She said Māori did not want to "run whānau off their land with guns, which is what happened to Māori", but to begin discussions about the best way for Māori land to be released from historical leases and returned.

"Fair compensation" could be paid from the government's Treaty settlement funds to individuals or organisations whose leases were ended, she said.

The Greens want to establish a commission of inquiry into the extent of land dispossession and the adequacy of redress, …
