Hon GRANT ROBERTSON: I know that the problem that New Zealand's housing market faces consists of both supply and demand challenges. I also know that this Government has been addressing those on the demand side with a ban on foreign buyers, on removing interest deductibility, on extending the brightline test, and, on the supply side, on building more houses. We have acknowledged that New Zealand has a housing crisis; the previous Government refused to acknowledge that, and that's how we've ended up where we are.
