Timing

01 July 2026

How it works

Marine Reserves Act 1971 (or relevant successor statute governing marine reserve establishment); South-East Marine Protection network designation.

Key context

Five new marine reserves come into force on 1 July 2026 along the Otago coast, protecting 308 sq km of habitat.This increases mainland NZ marine reserve protection area by approximately 50 per cent.Habitats protected include giant kelp forests, rocky reefs, offshore canyons, and deepwater coral communities.All fishing (commercial, recreational, customary) is prohibited in the new reserves unless specifically exempted by DOC or Kāi Tahu under management protocols.Check DOC website for the five reserve names, exact boundary maps, and any transition/exemption provisions for existing permits or leases.Kāi Tahu holds co-management authority alongside DOC; consult iwi on access, customary take, and cultural practice permissions.The sixth proposed reserve, Te Umukōau, is deferred pending further boundary consideration—track DOC consultation timeline.Tourism operators and recreational users must confirm which existing activities (diving, boating, wildlife viewing) remain permitted in each reserve under new management plans.

Wider effects

Te Tiriti (partnership decision with Kāi Tahu confirmed); Biodiversity strategy (record investment and predator control mentioned as complementary); Ocean health and waterways reform agenda.
