New Zealand's property tax landscape may change with the Labour Party's proposed Capital Gains Tax (CGT) for the 2026 election, which builds on the existing bright-line test.

If enacted, the CGT would start 1 July 2027, applying a 28% tax on gains from investment and commercial properties sold after this date. The family home would be exempt. Proponents cite tax fairness, while critics worry about compliance costs. Property owners should monitor the election before making decisions.
