A group of landlords has decried Labour's rent plan, saying they would push up rents if changes come into force after this month's election.
The 816 landlords answered a New Zealand Property Investors' Federation survey and 73.6 per cent said they would increase rents if a "suite of policies aimed at making it harder for them to provide rental properties was introduced", the federation said.
"More than half of all respondents (54.8 per cent) would increase weekly rental prices between $20 and $40/week."
The federation said the survey backed BNZ chief economist Tony Alexander that Labour housing policies would put pressure on rents.
In his latest economic overview, Alexander said that "Labour's policy mix has capacity to help constrain the pace of house price rises for lower-priced properties by boosting supply. But it will come at the price of higher rents."
