Auckland mayoral candidate Phil Goff says he wants new measures to discourage land-banking, such as tighter time limits on development approvals and consents.
Unveiling his housing policy at an event in West Auckland today, he said he would urge the government to ban foreign investors from buying existing homes.
It came as the average house price in Auckland was set to smash through the $1 million mark next month.
He also pledged to push for more social and affordable housing.
Mr Goff said he wanted to give the building industry more confidence about making a long-term commitment to house-construction in the city.
Much of the policy was in support of plans already underway in Auckland, such as increased housing density in the just-completed Unitary Plan, and an overhaul of the consenting system.
The left-leaning City Vision ticket, which includes both the Labour and Green parties and is endorsing candidates for council seats, formally announced its backing of Mr Goff at the event.
Mr Goff has chosen to run as an Independent and is not using Labour Party colours in the election.
City Vision spokesperson and councillor Cathy Casey said Mr Goff was the only candidate with the vision, skill and experience to lead the city.
She said City Vision would campaign for councillors who could work with Mr Goff.
