did a search on cheap flight tickets in the topic and it seems like Jetstar is the way to go.

I tried looking at their site where to plan for a trip to fly straight to Queenstown but Christchurch is the closest one they have. tried using the site to book a flight from kul to chc and back but the website just refreshed without giving me any flight date options. I'll just try again when I'm at a PC.

I'd like to know of anyone has tried kul to syd to chc and then return? is that a cheaper trip?
