Tried again several tmes swapping between TelecomData and TelecomDefault, finally getting sent to cwa.telecom.co.nz.
Then trying again and this time being sent to sphone.telecom.co.nz.
Cleared all cookies, cache etc and closed the browser between each APN switch.
Basically i'm getting inconsistent results here.
Trying to figure out a pattern of whats going on here.
