Well, it's going to be pretty warm, but likely rainy, so that's something to take into consideration. I guess it also depends on how you're getting around. For the sake of argument (and the fact that this is mainly directed at mom and uncle Chris) let's say you'll be travelling by car, so weight of your bag is not an issue.
Beyond the obvious (undies, socks, shirts, tooth brush) which I assume you can figure out for yourselves, here are some of my recommendations of items to bring.
- Rain is always a possibility in New Zealand, especially on the West Coast. Bring a rain jacket. I wouldn't bother with an embrella -- they're heavy and the wind that often accompanies said rain just destroys them (I speak from experience)
- It'll be fairly warm during the day (mid- to high-teens), so you'll likely want some summery clothes: capris, shorts, skirts, that kind of thing.
- At night it tends to cool down, even in summer (much of the heat here is due to direct sunlight -- when the sun goes, so does the heat). So be sure to also pack long pants, at least one sweater and/or a light jacket.
- About that sun -- it's no triffling thing here. The hole in the ozone layer is pretty much directly overhead and it's extremely easy to burn here. You'll want sunscreen and a hat with a brim (and I'd bring the sunscreen rather than buying it here -- it costs an arm and a leg compared to in Canada).
- With all the stunning scenery you'll be enjoying, a camera is definitely a must.
- For you bird watchers, binoculars might be appreaciated.
- Comfortable shoes are always a good idea no matter where you are, especially somewhere with such amazing walking tracks.
- If you're bringing electronics, obviously you'll want to have a converter for the plugs. The outlets here look like this:
