There has been coverage in the NZ press today about a scam website that is trying to capture passport details and other sensitive info:

The scammer site tries to look like the Immigration NZ site and has a very similar URL, so be careful.
Make sure you are on the correct site: http://www.immigration.govt.nz
The fake site has a - between the immigration and govt, not a .

It would be great if the real site used encryption to help verify its identity, but for some reason it doesn't.
