Tonga Island Marine Reserve runs alongside one of New Zealand’s most popular national parks, the Abel Tasman. A thriving local tourist industry supports all the marine activities, and visitors can easily combine land and sea adventures in their holiday.

The area is renowned for its golden sand beaches, intimate coves, and excellent summer weather. There is a New Zealand fur seal colony on Tonga Island.

The clear warm waters of the reserve make it incredibly popular with kayakers and swimmers, and trampers on the coastal track will sometimes pop into the water with a snorkel to cool off. Underwater visitors will see tumbled rock and bedrock reefs, inhabited by numerous grazing invertebrates, with sandy-bottoms extending beyond.

Kayakers will often see little blue penguins along this coast and may occasionally be rewarded with an encounter with a pod of dolphins. Because many local estuaries are also protected, visitors may see some of New Zealand’s rarer shorebirds.

Activities in Tonga Island Marine Reserve

Kayaking, rock-pooling and picnicking around the golden sandy coves at Tonga Island Marine Reserve is an idyllic way to spend a day.

The best snorkelling is among the rocks between Tonga Quarry and Foul Point. Scuba diving is most rewarding on the reefs around Tonga Island or in the north of the reserve. Seaweeds are confined to a narrow band along the low water mark, but this makes it easy to see kina and turban shells grazing on the seafloor and boulders.

If you are planning to stop at Adele and Fisherman islands, plan and prepare before you go to ensure you do not accidentally take pests, such as mice, rats, non-native ants and weeds, onto the islands. Tonga Island is a seal breeding colony and not suitable for public access. Seals can move faster than you think, and have a nasty bite.

No fishing or shellfish gathering from either boat or shore is allowed in Tonga Island Marine Reserve.

People are welcome to visit and enjoy the reserve – picnicking, swimming, boating, diving and photography are all encouraged. Educational and scientific activities are allowed too, provided they do not unduly disturb or endanger the reserve’s plants and animals.

If you see people taking fish within the marine reserve, please report the activity to the Department of Conservation as soon as possible.

Plan & prepare

Getting there by sea


Seaweed underwater at Tonga Island Marine Reserve

The nearest boat ramp is at Totaranui, 5 km north of Awaroa Head. There are others at Tarakohe near Takaka, and at Kaiteriteri and Marahau in the south.

Water users should be wary of unmarked reefs and tidal changes. Sea conditions are often calm in winter but stiff sea breezes occur daily in summer and there is little shelter to be found along rocky sections of the coastline during storms.

Getting there by land

Foot access to the reserve is along the coast track from the north or the south. The nearest car park, at Awaroa, is 33 km from Takaka. Allow a full day for a return trip from the car park to Tonga Quarry. Before setting out, check the tide tables because it is only safe to cross Awaroa Inlet within one hour 30 minutes before low tide and two hours after. Onetahuti estuary can only be crossed safely three hours either side of low tide.

From Awaroa Hut, head east to the mouth of Venture Creek and climb up to Tonga Saddle. From here there is an easy descent to Onetahuti Beach – your first contact with the marine reserve. Tonga Island lies directly offshore from here.

Transport services

The Abel Tasman coast is well served by bus, boat and kayaking companies. Information on their services is available at i-SITE visitor centres in Motueka, Takaka and Nelson.
