Prime Minister John Key has underlined the importance of speeding up building consents to make homes more affordable after the Government's major reforms of the Resource Management Act hit a roadblock.
Mr Key admitted the proposed RMA legislation would need to be changed after National's support parties United Future and the Maori Party made a rare, joint statement of opposition to the reforms.
National had the support of Act for the bill, which is still being drafted, but needed one more vote to get it over the line.
Labour and the Greens called for the legislation to be dropped altogether while New Zealand First said it was premature to make a decision before the bill had been introduced.
United Future and the Maori Party were especially critical of the proposed amendments to the RMA's principles, which would give greater emphasis to economic development in the approval of consents.
