Current NZ bright-line rules: since 1 July 2024 the bright-line period is 2 years for any property sold on or after that date, regardless of purchase date. Older sales (before 1 Jul 2024) fall under the previous bands: 10-year for property bought 27 Mar 2021 – 30 Jun 2024, 5-year for 29 Mar 2018 – 26 Mar 2021, 2-year for 1 Oct 2015 – 28 Mar 2018. New-build exemptions under the old rules aren't modelled here. Always consult a tax advisor.
