🇳🇺Niue

Niue has no local recompression chamber. Dive within training and conservative gas and depth limits; verify the operator's emergency oxygen, incident plan, boat communications and evacuation procedure before getting on the boat. Cavern and chimney dives require training specific to overhead environments; even an apparently open air pocket may be unsafe to breathe. Avoid solo freediving, unsupervised deep breath-hold work and self-guided wharf or open-coast entries. If decompression illness is suspected, activate 999, arrange medical evaluation immediately and follow qualified medical advice; trained responders should provide emergency oxygen where available. Keep records of dives and follow professional no-fly guidance before the limited weekly flight.

Niue Foou Hospital provides the principal local medical response, but facilities are limited. Australian Smartraveller confirms there is no hyperbaric chamber and serious dive injuries may require medical evacuation to New Zealand. Plan for delayed transport and ask your insurer specifically about diving, helicopter or fixed-wing evacuation and recompression costs. Keep personal medication, first-aid supplies, wound-care items and a local communication method. Local emergency service number is 999; the hospital is listed on 4100, with 4202 also published on the Niue health flyer. For weather warnings, follow Niue Met and emergency management authorities.

In 2020 Niue created the Moana Mahu Marine Protected Area, a strict no-take zone covering about 40 percent of its EEZ. The Nukutuluea multiple-use marine-park framework extends management across the entire EEZ and territorial waters. Do not fish or collect animals or coral in restricted zones; verify any permit, closure or traditional access rule with local authorities. Licensed whale operators alone may provide in-water humpback encounters; do not chase, touch, feed, block or dive down toward whales. Some sea tracks or pools temporarily close for kaloama spawning; signs supersede published access guides. Keep fins off living coral, avoid damaging fragile limestone and respect village-owned land.
