Once, whio probably lived throughout much of Aotearoa, inhabiting lowland rivers as well as the mountain headwaters to which they're now restricted. The sad fact is that now, with few exceptions, the lowland forests have long gone and as soon as the rivers leave the mountains and begin to make their way through intensively farmed lowlands, they begin to deteriorate. It's rare to find water as clear and clean as this outside the headwaters.
