It’s hard to suppress my feeling that Green Party MPs inhabit another planet. Their policy announcement at the weekend that they would introduce rent controls and hold increases to 3% pa told me that they know nothing about the history of housing or rent controls, either in New Zealand, or anywhere overseas. The Greens’ great nostrum for helping low income people in 2023 was first tried using a series of Rent Restriction Acts during World War One, more than a century ago. The idea proved to be disastrous. And when revived by the First Labour Government it was no more successful.
