2025 New Zealand National League

The 2025 New Zealand Men's National League (known as the Dettol Men's National League for sponsorship reasons) is the fifth scheduled season of the National League since its restructuring in 2021; the 2021 National League was cancelled due to the COVID-19 pandemic in northern regions. 32 clubs compete in the competition, with four qualifying from the Northern League, three qualifying from the Central League and two qualifying from the Southern League for the National Championship phase. Auckland FC Reserves and Wellington Phoenix Reserves qualify automatically for the championship phase. Each team can field a maximum of four foreign players as well as one additional foreign player who has Oceania Football Confederation nationality. Over the course of the season, each team must also ensure players aged 20 or under account for 10% of available playing minutes.

The qualifying league fixtures were announced on 28 February 2025. The Northern League starts on 15 March 2025 with the Central and Southern leagues starting on the 29 March. The Northern and Central leagues concluded on 30 August 2025 with the Southern League concluding on 31 August 2025.
