Replying to Coming to NZ in August

Hey dudes. I will be heading down to NZ at the beginning of August and will be staying till the 10th of September. First 2 weeks I will be travling around, and then the next 3 weeks I stay in Wanaka.

I have a couple of questions.

Which resort's got the best halfpipe? I like them big (6 m) and smooth and shaped daily (or close to).

Are there any special ski pass deals I need to know about for around Wanaka? I was thinking about getting a season pass for Snowpark and then a 10 non-consecutive days pass for Treble Cone. Will I get ripped off like this?
