Allports Island
Boat-access deep wall and training site near Picton.
ScubaBoat EntryIntermediate
Deep
Local operator required
Most visiting divers reach Allports Island with Picton or Waikawa-based boat operators rather than as an independent shore dive.
Usually reached by dive boat from Picton or Waikawa, with sheltered Sounds access, cold water, and quick progression from shallow rock to deeper training terrain.
About Allports Island
Allports Island is a boat-access wall and training site in Queen Charlotte Sound opposite Waikawa Bay, where deep water wraps close to the shoreline and lets divers move quickly from a shallow rocky margin into steeper terrain. It is commonly treated as a practical Marlborough Sounds dive for skill work, depth progression, and relaxed exploration rather than for one headline feature. Shallower sections hold anemones and fish around the rock, while deeper water is known for dense tubeworm growth that gives the wall extra texture. The site suits divers who are comfortable with colder New Zealand conditions and want a straightforward Sounds dive with real depth nearby, but without the bigger logistics of outer-coast or major wreck trips.

Allports Island works well for deep-dive practice and wall-style exploration because the bottom drops away quickly and lets teams combine shallow setup with deeper water nearby.
