"We can't allow people to come in and destroy our oceans without allowing us to have our say."
Mining ban gathers more support
Ngarewa-Packer, who is also a former Ngāti Ruanui kaiarataki, said every signature in the petition will be heard.
"You matter to us - we know what it's like to be young activist. As a not-so-young activist, never doubt the mahi that you do, so that this place up here [Parliament] stops burying its head in the sand and starts to admit that it's got it wrong.
"To sit there and see my people back in the EPA last week, to see them back in court trying to prove that this should never be here, we should never be here. We should never have to protect our ocean to the depth and extent that we are at the moment."
Te Rūnanga o Ngāti Ruanui has fought Trans Tasman Resources all the way to the Supreme Court to prevent iron sands from being removed from Pātea.
Ngarewa-Packer says she is humbled to see 36,000 signatures on the petition.
"The first petition we brought here was about eight years ago and it had 6000 signatures. It just goes to show how significant this kaupapa is and, particularly for people like mine back home, when the cost of living is so expensive, the last thing we need is uncertainty around our kaimoana and our moana."
