I guess it's horses for courses, but wear a heavy cotton shirt in the NZ bush and you'll end up with hypothermia within the day, even in summer it is not a good idea if you are heading for the tops, as it will get damp from sweat at lower altitudes then be bloody cold once you get above 1000m or so and clear the bushline.
Cotton is just about the worst thing to wear here, heavy when wet, wicks away heat faster than even bare skin, and will stay wet for ever (or at least until you get home).
