It appears that Wellington airport is effectively closed with Air NZ and Qantas showing all flights to/ from Wellington are cancelled for this evening. Jetstar shows it is operating [albeit with massive delays], although I suspect that is more to do with their crappy customer service not updating their website.
No pictures from the airport, but here's a couple of others which help to show what it's like. There is ice everywhere, it's bitterly cold and altogether rather miserable. What you can't see of course, is the wind... the house is shaking, or the thunder and lightening :-)
