AI summary

New Zealand has a 'quasi' capital gains tax called the bright-line test for residential properties. The Labour Party has proposed a new CGT starting 1 July 2027, if elected. It would apply a 28% tax on gains from commercial and residential investment properties sold after this date.

The family home, farms, and KiwiSaver would be exempt. Supporters believe it creates tax fairness, while critics worry about compliance costs. Property owners should await the election outcome before making any decisions.
