Diving in New Zealand
Including Kaikoura Submarine Canyon, MSV Canterbury Wreck, and Milford Sound. On the map.
The vibe
Submerging in these island waters feels like exploring rugged underwater cathedrals carved from ancient volcanic rock, complete with towering kelp stalks swaying in the current and schools of red mado hovering in deep archways. The deep-water visibility peaks during the cooler, settled winter months when the southerly swells back off. Operators run well-drilled charter trips out to iconic marine reserves, striking a comfortable balance between professional organization and laid-back coastal hospitality.
