Avarua Passage: boat drift through Rarotonga's harbour pass.
Avarua Passage is a boat-access drift through Rarotonga's harbour pass, where the sand and reef edge create a fast-moving channel rather than a broad reef run. Divers stay with the current as the passage draws turtles, sharks, eagle rays, and barracuda through the water. It is a current-driven site that rewards timing, control, and a tight team. The sandy route and harbour-facing line make it feel like a moving-water corridor more than a static reef.
Site Conditions
Safety Notes
This is a fast-current drift, so keep a tight team and avoid treating the passage like a static reef stop.
Access Restrictions
Boat/mooring start, current planning, and guide awareness of harbour traffic are important.
Legal Notes
Stay with your guide and respect harbour traffic and local pass rules.
Community notes to help plan your visit.
Scuba Diving
Follow the sand and reef edge from the mooring into the harbour for a classic drift run.
Freediving
Not a freedive-first site; the current and depth make scuba the practical choice.
Snorkeling
Snorkeling is secondary here because the pass is best experienced as a drift dive.
