Capital gains tax in New Zealand, explained without the spin
It's the defining economic argument of this election, and most coverage assumes you already know what it means. Here's the actual mechanism.

Take the quizWhat it actually is
Income tax is charged on money you earn. A capital gains tax is charged on the profit you make when you sell an asset for more than you paid.
If you buy a rental for $600,000 and sell it for $800,000, the $200,000 gain is currently untaxed in most cases. Someone earning that same $200,000 from wages pays tax on every dollar. That asymmetry is the whole argument.
What's on the table in 2026
Labour proposes a 28% tax on profit from selling investment property from 1 July 2027, with every dollar ring-fenced for health. It excludes the family home, farms, KiwiSaver, shares and businesses.
The Greens go further, proposing a 33% capital acquisitions tax on assets or gifts over $1 million alongside an annual wealth tax. National, ACT and NZ First all oppose any new tax of this kind.
Who would actually pay
Under Labour's version, roughly nine in ten New Zealanders wouldn't. If you own only the home you live in, it doesn't touch you. If you own a rental or a bach, you'd pay tax on the gain when you sell, and only on gains made after the start date, not on what the property has already earned.
The genuinely contested question is what happens to renters. Supporters expect house prices to cool slightly. Opponents expect landlords to pass the cost on as rent. There is no settled New Zealand evidence either way, and anyone telling you otherwise is guessing.
Home ownership is at its lowest rate since 1951, about 65% of households, down from a 74% peak in the 1990s.
