The Labour Party has pledged to repeal the Māori land reform bill if it becomes the government.
Iwi leaders and politicians have voiced their opposition to Te Ture Whenua Māori Bill, with the Māori Party's newest ally, Hone Harawira, calling it a poisonous cancer.
Labour Ikaroa-Rāwhiti MP Meka Whaitiri said her party would repeal the bill, which was due to be made law next month.
Māori Party co-leader Te Ururoa Flavell told RNZ the government had consulted widely, made 129 amendments and removed 29 clauses.
But Ms Whaitiri has criticised that, saying the government was creating policy "on the fly".
