Both my car license and WOF expire in June when I'll be out of the country. This afternoon I called the transport agency http://www.nzta.govt.nz/vehicle/regi...licensing.html to ask how to deal with this problem. I'm posting information here in case anyone else is curious about the process.
The Warrant of Fitness isn't a problem - I can wait until I return and can drive the vehicle to a WOF station (with an expired WOF) providing I have an appointment with the station and can prove that I was out of the country.
Renewing a car license can be done online but not more than a month before it is due to expire.
I forgot to ask how much it will cost to renew my car license!
