The Opportunity Party says a property tax shake-up's front of mind.
The Party needs 5% to break into the Beehive, and has been scoring between 3% and 6% in polls.
The centrist party's proposing a blanket Land Value Tax, claiming it'll bring house prices down by up to 15%.
Leader Qiulae Wong told Kerre Woodham they want land banking to become less attractive.
She says it's about shifting the income tax burden on to land tax, so people can't just grow wealth from property.
