At the southern tip of New Zealand, Stewart Island's rugged coastline hosts a small but dedicated great white shark cage diving operation in cold, nutrient-rich Foveaux Strait water where sharks patrol fur seal colonies. Expeditions feel remote and raw compared with Mexico or Australia, with fewer boats and longer weather windows required. Austral autumn from March through May delivers the most consistent encounters before winter seas close access.

Up to 78% sighting chance in Stewart Island (New Zealand). Best months: April, March, May.
Operators typically run December through June, with March through May offering the most consistent encounters before winter seas and Foveaux Strait swell limit access.
Multi-day cage packages typically run 1,800 to 2,800 NZD per person (2026 prices), reflecting remote logistics, small boat capacity, and weather contingency days built into most itineraries.
A single licensed operator runs surface cage trips from Oban. Divers use snorkel or surface-supplied air in floating cages; no submersible or open-water diving is available.
Water temperatures often sit between 10 and 14 degrees Celsius with sharp thermoclines in Foveaux Strait. Thick wetsuits or drysuits, hoods, and cold-water experience are essential for comfortable cage time.
Fly or ferry from Invercargill to Oban on Stewart Island, then join the operator's boat. Most trips require two to four nights on the island because weather windows are narrow.
