My RTW honeymoon is just hemorrhaging days and I need to cut some days here or there. Queenstown is one possible place to cut a day. Originally planned 5 days, 4 nights. The cut would bring it down to 4 days, 3 nights. Arrival/Departure on the once-daily QF from AKL. Timing is roughly the third or fourth week of July.

So how much is there to do in the winter?

First afternoon maybe exploring the area? Jetboating (in the winter???)
Second day (first full day) maybe skiing or snowboarding followed by night out around town.
Third day (second full day) maybe day-trip to Milford Sound.
Fourth day probably just a matter of getting up and going to the airport.

Am I missing something I should seriously consider, that would require leaving it at 5 days, 4 nights?

Thanks.
