as a nz citizen you are entitled to full medicare cover. yahoo. you need to take out medical insurance including basic hospital cover ($150 per month?), a neuro visit costs about $200 of which you get about $100 back from medicare. if you get dbs i estimate you need to top up your insurance by $20,000 or so.
meds are expensive until you reach the annual $1700 'safety net' when they become cheap.
on the other hand you get treated like a private patient ie accurate appointment times, civil nurses etc
its basically half way between the nhs and the usa system.
