AI summary

New Zealand has a 'quasi-capital gains tax' via the bright-line test, which applies to recently sold residential properties.

The Labour Party has proposed a new capital gains tax, starting 1 July 2027, if elected. It would apply a 28% tax on gains from selling commercial and residential investment properties. Key exemptions include the family home, farms, and KiwiSaver. Property owners are advised to await the election outcome before making decisions and seek professional advice if the law changes.
