NZ tourist boards seem to have an obsession with outdoor baths!! With most of the houses here stuck in the 1970s with their ancient storage heater ideas and absence of central heating (this is a real live deal breaker for many emigrating Brits) perhaps this is the most cost-effective and likely way of having a soak. The deal with them is you fill the tub with water, light a fire under it, wait for it to heat and then strip off and enjoy the great outdoors au naturel, star gazing and enjoying the bird song etc. Nice idea but for the sneaking suspicion that one might 'boil ones butt off' in the process, or at least suffer some serious third degree burns!! Not so, for the kiwis, have developed an ingenious contraption that shields said rosy cheeks from the scalding bath's bottom ie a plank of wood. It does actually work although it involves some careful balancing as wood floats so you can't get all of your body under the water, all of the time. I opted for the legs out, rest of body under the water, approach - and despite getting some nice mozzie/sandfly bites around my ankles I'd do it again in a flash, despite the rain.
