William Trubridge

Trubridge was the first diver to go deeper than 100 metres (330 ft) without oxygen and as of 2013 held the world record in the free immersion and constant weight without fins disciplines.

[4] On 15 February 2019 Trubridge became the first man to complete an 'underwater crossing' of one of the major channels, swimming across the Cook Strait as a series of 934 breath hold dives.

He wore fins and swam with a dolphin kick horizontally underwater at a depth between 3–5 meters, surfacing only for short recoveries during which he remained immobile.

The crossing took 9 hours 15 minutes and was done to raise awareness of the plight of New Zealand's Hector's and Māui dolphins, which are both threatened with extinction due predominantly to over-fishing in their ranges.

In the 2021 New Year Honours, Trubridge was appointed a Member of the New Zealand Order of Merit, for services to free diving.
