In this episode of Pure Fly New Zealand, Producer Nick Reygaert and his brother Chris push deep into the mountain headwaters looking for trophy Rainbow Trout. Local anglers know that the largest specimens tend to push hard into the smaller streams of the upper river reaches, where the ecosystem favours good spawning. The result is incredible sight fishing in inches of water, every fly anglers dream! This kind of angling requires hours of trekking to find the magic pools where the fish are holding, but it pays off. What Nick and Chris find is amongst the most fertile and untouched water on the planet.
