New Zealand has a limited bright-line test, but the Labour Party has proposed a wider Capital Gains Tax (CGT) for the 2026 election.

If enacted, a 28% tax would apply to gains on investment and commercial properties sold after 1 July 2027, with family homes exempt. Supporters argue it promotes fairness, while critics highlight compliance costs and its narrow focus.

Property owners should monitor the outcome and seek professional advice if the law changes.
