That's a good route! The Milford Track would be great fun, it'd take a chunk of your time though and we've just start the "Season" where hut bookings are required - if you haven't booked already they my be all taken anyway!

I'm trying to think of some that are 1-2 day but not coming up with much. There's some great 6-7 hour returns, but can't think of any that would require a night and would fit your plans.

The cool thing about your route is that aside from Te Anau, Queenstown and Wanaka, is you're avoiding all the main centres in the south island so you'll get to experience it all on your own :)

Flying into Queenstown is great, I hope you've allocated a day or so to explore the town. It's small, but there's a lot to do and you'll want to take a photo ever 10 metres. Te Anau is like a sleepier version of Queenstown, not as much to do but damn if it isn't peaceful. Wanaka is a bit unique, has a bogan culture mixed in with very rich locals. A stunning place though, somewhere in my post history on here I put up a photo in wanaka when I was at a wedding.

The West Coast that you're travelling up towards Nelson is just awesome. Few people, all lush forest. There's a cute wee area in Westport that (if you have a day) will help you craft a sweet knife from scratch. My flatmate did hers this year and apparently its a very rewarding experience - I'll try find the name when I'm back at my computer!

I think that trip looks very solid and enjoyable. One thing I'd recommend is planning for longer driving stints, our roads are not that great, and our average driver is quite aggressive. You may find yourself plodding along at a leisurely rate as people hoon past you! Don't let them bully you and just turn off when you can if you want to take in the scenery (which you should!).

The weight lifting is going well thanks, the numbers are increasing! Just a bit slower as I become more advanced and the progression less linear. All in good time though, makes every goal taste the sweeter as I hit it.
