HMNZS Moa - Tulagi & Florida Islands
Site Overview
HMNZS Moa is one of the signature dive sites of Tulagi & Florida Islands in the Solomon Islands. The 51 m New Zealand corvette HMNZS Moa sank in 1943 and lies at 20 to 35 m, shallow enough for advanced recreational divers, with a bow gun, anti-submarine mortars and rich macro life. The site reaches a maximum depth of about 35 m, with an average depth near 28 m, and its wreck topography is draped in metal and coral. Marine life is the headline attraction, with nudibranch, lionfish, moray eel, glassfish, soft coral, grouper regularly recorded here, drawn in by the mild currents and the rich Coral Triangle productivity of the region. Visibility typically ranges from 15 to 32 m, while water temperatures hold a consistent 27 to 30°C year-round, comfortable in a 3 to 5 mm wetsuit. Conditions suit advanced divers, and with the right guide the site delivers both the drama of its wreck and intimate encounters with the smaller residents. Local operators run regular trips from Tulagi, and the protected, low-tourism setting keeps coral cover dense and fish life abundant, making HMNZS Moa a genuine standout on any Solomon Islands itinerary. Divers who time their visit to the calm season will find the most predictable conditions, though the site rewards repeat visits across the year.
Dive Briefing
"The dive at HMNZS Moa begins with a thorough operator briefing covering the site layout, expected marine life and emergency procedures, followed by a controlled entry and a short transfer from Tulagi. Descending toward the wreck profile, divers are immediately surrounded by nudibranch, lionfish, moray eel, glassfish, soft coral, grouper, with the reef and structure revealing more detail the closer you look. The maximum depth reaches about 35 m while the average sits near 28 m, so a dive computer and disciplined gas planning keep the profile safe and comfortable. Currents are described as mild, and the guide chooses the entry time to make the most of slack or mild flow, using a reef hook or DSMB when needed. Neutral buoyancy protects the fragile coral and the group stays close to manage depth and any surge. The safety stop is completed in open water on a DSMB, and the boat follows the bubbles to collect divers at the exit point for a relaxed return to base. The HMNZS Moa is best dived as a deeper recreational dive from 20 to 35 m on a calm day, with the bow gun and anti-submarine mortars most photogenic on a slack window. Mild currents ease the approach, and a morning dive gives the best visibility. Water stays 27 to 30°C, and a 5 mm wetsuit suits the depth."
