Cost of Healthcare / Medicare in Cook Islands

Hello

Can anyone inform us of Healthcare / Medicare costs in Cook Islands.

The Cook Islands Ministry of Health has a very nice website.
http://www.health.gov.ck/
Unfortunatly they do no list costs of different services.

Is it free?
How much does a nurse or doctors visit cost?
How much is a day+night at hospital including food?
How much is annual check-up?
How much is it to call in to have a prescription?
Is there a annual max amount one can pay for health/medcare and have the rest for free?
