Other Cook islands customs information

Typhoid immunisations should be up-to-date.

Food drink: Tap water is relatively safe but may cause mild abdominal upsets. Bottled water is available and is advised for the first few weeks of the stay. Milk is pasteurised and dairy products are safe for consumption. Local meat, poultry, seafood, fruit and vegetables are generally considered safe to eat.

Other risks: Hepatitis A occurs in the region and hepatitis B is endemic. Inoculation against Tetanus is recommended.
Bathers should be aware of the possible hazard caused by sharp coral reefs.

Health care: There is no direct reciprocal health agreement with the UK, but such an agreement exists with New Zealand which may, in some circumstances, also apply to the Cook Islands; enquire at the Cook Islands Representative (see Contact Addresses section). There is one government hospital (on Rarotonga).
