My wife and I are flying to/from Fiji and Samoa in mid-January '14 through Christchurch and decided to stay over for 3 days to see something in NZ as it will be our first time there. So from the internet I've gathered that we want to drive either to the Westland NP area and one of the glaciers, or to the Mt. Cook NP area with the Tasman glacier and lakes, etc. We're mostly into walking/hiking from short up to half-day, maybe a little paddling with a view if that's a possibility. I don't think helicopters is our thing, and we've been on a glacier before (Icefields Parkway in CA). So which way should we go? I'd really appreciate hearing people's opinions.
