Diving at Three Kings Islands

This article is intended to provide the already qualified scuba diver with information which will help to plan dives in the waters of the Three Kings Islands of New Zealand. The information may not be up to date, and is not complete. Use it at your own risk.

Understand

The Three Kings Islands is a small archipelago of 13 islands about 55 km (34 mi) to the northwest of Cape Reinga, the northwesternmost point of North Island, New Zealand. The archipelago consists of two groups: To the west, the small islands, West Island, Princes Islands and Southwest Island, and to the east, Great Island and Northeast Island. They are on the Three Kings Bank which is separated from the New Zealand mainland by an 8-km-wide, 200- to 300-m-deep trough.

The islands are called Manawa-tawhi or Ngā Motu Karaka in Māori. They were named Drie Koningen Eyland by Dutch explorer Abel Janszoon Tasman in 1643 on 6 January, the date on which the visit of the biblical three kings to the Christ child is celebrated.

Three Kings Island is a nature reserve administered by the Department of Conservation.

General topography

The islands have a land area of about 4.86 km².

They are situated where the South Pacific Ocean and Tasman Sea converge, in two groups, with four main islands and a number of smaller rocks.

King Group

Great Island or King Island, known to Māori as Ohau or Manawatawhi, is the largest by far with an area of 4.04 km². The island reaches a height of 295 m.
North East Island, about 1 km northeast of Great Island has an area of 0.10 km² and reaches a height of 111 m.
Farmers Rocks, 0.8 km east of Great Island, are 5 meters high and just a few hundred square meters in size.

Southwest Group

South West Island is the second largest of the Three Kings Islands with an area of 0.38 km² and height of 207 m. It is about 4.5 km southwest of Great island.
The Princes Islands comprise seven small islets and a large number of rocks with a total area of about 0.2 km². They extend from about 600 m west of South West Island for about 1.8 km further west. The north-eastern islet is the highest at 106 m. The smallest islet is Rosemary Rock.
West Island is the third largest island, with an area of 0.16 km². It is about 500 m southwest of the Princes Islands and is 177 m high.

Climate, weather and sea conditions

The islands are exposed to wind and swells from all directions, but are slightly sheltered from south easterly swells by the bulk of North Island. The Islands are small and rainwater runoff will not carry much silt into the water, so the visibility is generally good. There are not many good anchorages — the ground is usually boulders and bedrock, so the anchor may hold well enough, but can easily foul.

Water temperature may be as low as 14°C

Marine ecology

Although the water temperature is more characteristic of temperate waters, the fish and invertebrates include several tropical species, as is the case for several of the offshore island groups of the east coast of North Island, which is in the path of the East Auckland current.

Equipment

Standard recreational diving equipment is appropriate for most dives. Wet suits are sufficient most of the time, but for long dives a dry-suit may be preferable if the water is cold.
