The latest REINZ data shows Auckland median house price has gone up $145,000 in 12 months.
In 2017 Labour campaigned on abolishing the rural urban boundary which artificially restricts land supply. It was one of their best policies. In 2020 they quietly announced that they had reneged on the policy.
So the increase in house prices is not an accident. They have deliberately decided to renege on a policy which would have lowered the cost of land.
