Hi EB,
I'm all set for Skiing in August and can advise the following:
1. Go to Queenstown or Wanaka.
2. Flights to Christchurch S$1000 via Air NZ Web.
3. Internal Flights Christchurch to Queenstown call Air NZ direct in NZ (half price compared to booking in Sin.). They send an eticket.
4. Car Hire NZ$79/day from Apex rental for Subaru Legacy Estate
5. Accom. 4 bedroom house in Arrowtown for NZ$160/day. Find accom. on
www.purenz.com Other accomodation links are via Friars/Heritage and Character/queentown plus many more.
6. Ski Tickets at the resorts NZ$275 for 5 days. See
www.nzski.com 7. Ski hire at Brown's Ski shop in Queentstown. NZ$30/day.
8. For Heli-Skiing NZ$600/day.
9. Used AIG annual insurance cover as they cover all amateur sports.
It took a little work but from the reports it should be worth it!
