Well, I can see two local townships on the map but I can't select either of them with the 'move pin' dialogue - I guess the software being used on the site doesn't know much about New Zeland (and certainly doesn't understand our zip codes!).
If anyone is driving from West Melton to Rolleston, about 25km west of Christchurch on the South Island, you'll be able to see the sawdust from the blades I'm carving over the holidays :-)
Cheers all.
