The test itself is a joke and no-one has been known to fail it. Driving is on the left-hand side of the road. Currency is the New Zealand dollar but you can buy souvenir Cook Islands coins and notes. Dress is casual but, in common with most Pacific islands and Asia, it is considered offensive to wear almost nothing when visiting towns or villages. Topless sunbathing is definitely a no-no.
Most hotels have phone and fax facilities.
Visitors can also get these, plus e-mail and internet services from Telecom Cook Islands in Avarua. Electrical power is 240 volts 50 cycles, as for New Zealand and Australia. In some cases, a two pin adapter may be required. Some accommodation providers can supply connections for 110 volt electric razors. Automatic Teller Machines are available on Rarotonga.
