New Zealand repeaters

Just arrived in ZL-land and tried listening to the UHF repeaters in Auckland, North Island. Although hearing stations on the linked national network of repeaters on 439.875MHz in Auckland, I have been unable to access it. This may be because my VX2 signal is just too weak or I may need a CTCSS code or DCS code I don't know.

Anyway, the scenery here up on the Bay of Islands at Russell is just breathtaking so who needs ham radio right now....
