A recent Newshub - Reid Research poll showed the highest public support yet for the Government revisiting a capital gains tax, with almost 55 percent of New Zealanders agreeing and only a third disagreeing. It's no secret in this Chamber that the Greens have long called for a comprehensive capital gains tax and, of course, wealth taxes. We know that tax is not a silver bullet, and we know that we need to also have more public housing, rent controls, and a rental warrant of fitness to ensure everybody in this country, regardless of whether they own or they rent, has a warm, safe, dry, secure home. But tinkering simply will not cut it, because even if house prices were to fall by 10 percent this year, as some economists are indeed predicting, we would still be only back to where we were about six months ago.
