How long is the bright-line period now?

Two years, for residential property purchased on or after 1 July 2024. Properties bought between 27 March 2021 and 30 June 2024 were subject to older 5- or 10-year periods.

Does the bright-line test apply to my own home?

Generally no — the main home exclusion covers the property you predominantly live in, though partial taxation can apply if you rent it out or hold it through certain structures.

Is the bright-line test a capital gains tax?

It functions like one within the window: gains on sales inside the bright-line period are taxed as income at your marginal rate. Outside the window, gains on properties bought for long-term rental are generally not taxed.

The bright-line test explained: current NZ rules

The bright-line test taxes the gain on residential property sold within two years of purchase — for properties bought on or after 1 July 2024. Sell inside the window and the profit is taxable income at your marginal rate; hold past it and, for a genuine long-term rental, the gain is generally not taxed.

Which period applies to you

The rules have changed repeatedly, and the date you entered the agreement determines your period: purchases from 1 July 2024 get the 2-year test; purchases between 27 March 2021 and 30 June 2024 were under the 10-year test (5 years for new builds); earlier purchases had 5- or 2-year periods. If you bought during the 10-year era, your clock may still be running — check before you list.

The main exclusions

Your main home is generally excluded — the property you predominantly live in. Inherited property and transfers under relationship property agreements are also excluded. The exclusions have edges (living in one unit and renting others, long absences, trust ownership), and those edges are where people get caught.

The traps

Three catch people out. The clock usually starts at settlement but ends at the date you sign the sale agreement — not the settlement of your sale. Adding or removing owners (including moving property into a trust or LTC) can restart the clock on the transferred share. And intention matters beyond bright-line: if you bought with the intention of resale, the gain can be taxable under ordinary income rules regardless of how long you held.

What it means for strategy

For buy-and-hold investors the 2-year window is rarely binding. It matters most for renovate-and-flip strategies — where the gain is usually taxable anyway under intention rules — and for anyone forced to sell early. Model your hold period before you buy, and get accounting advice before transferring ownership of anything you've held less than two years.
