jeffnz: bit of info on xda-developers not sure if that will help at all but if its locally purchased it may indeed need an update from Telecom

Telecom don't sell the G2, it's only (officially) available through Harvey Norman locally, who claim it is 2degrees branded (But I understand that is likely due to the relationship HN have with 2d rather than it actually being a 2d-branded device). Telecom have nothing to do with the update process for this device, so it'll be updated on LG's schedule and may not resolve the issue at all.

Feedback best sent to LG, although, as Freitasm notes, LG's Australia-based frontline support are not the most aware of the goings-on in the NZ market (Matches my experiences as well).
