Now that my hoped for relocation to Perth is not going ahead

I'm going to have to make do with windsurfing holidays. I'm going to Wellington over Xmas to visit the GF's rellos. They happen to live very near the water and will loan us a car with roofracks for our stay. Of course it's very windy in Wellington.
I've heard there's no places to hire kit in Wellintgton so am looking at taking a board and two sails etc with me. I've had a look at the QANTAS website and am unsure whether they'll take my gear or not when we fly.
Has anyone ever taken gear to NZ or been able to take gear with them when on holiday without any major dramas? Any advice would be appreciated. Recomended airline?
