In reply to echo34:
Probably the best place to look for single day scrambles is just to find a list of high peaks, and read about the approaches. I'd recommend these to you from personal experience:
- Ngauruhoe & Tongariro - approach via a very popular track, and then the scramble up to Ngauruhoe takes an additional 90-120 minutes. It's technically very easy, although you will need to be comfortable with steep and loose scree (plunge steps, crossing scree fields, etc). Whole day takes about 8 hours or so.
- Taranaki - approach via another popular track, then 2 hour scramble on sharp, but solid rock to the summit. Technically very easy. 6-7 hours round trip.
And also I highly recommend getting into tramping. You might think that it's easy because it's just walking, but you'd be very wrong. It's totally different from hillwalking because you're sometimes at the mercy of the track (or more accurately - finding markers if it's not a well trodden track). If you get lost in the bush, it could take days to find a way out. Some people simply don't find their way out. The tracks can require good balance and footwork (stepping over/on tree routes and rocks) and hands are often needed to climb up or down steep sections. Because there's no pub/shop at the other end, you have to carry days worth of food - which consequently makes walking over tree roots and climbing things a lot harder. Similarly you sometimes need to cross rivers that can be many metres wide, up to chest deep, that can be metres deeper again when in flood, with the only alternative option being a 2 day trip over a mountain pass to another far away road (wait there rather than attempt crossing, never cross a river that you are not in control of). There are many cases of people just going missing entirely (never to be found) when out on their own as well - always let someone know your plans (including escape routes). Sounds great just writing it out doesn't it.
All in all - have a great time, and let me know if I can answer any other questions
