About this water

The Waitahanui is a jewel — a short, cold, spring-fed river that stays clear and fishable when the freestone rivers are blown out, holding visible rainbows and browns in its glassy pools. Its mouth is one of the most famous pieces of trout water in New Zealand, the 'Picket Fence' of wet-fly anglers fishing the rip into the lake. Upstream it is a clear-water river that rewards a careful nymph and a quiet approach to fish you can often see.

Under the surface

A short, spring-fed river rising from the pumice country south of Taupō township and running clear and steady to the lake, its lower reach famous for the 'Picket Fence' of anglers lined along the rip at its mouth. Cold, clear and stable where the rain-fed rivers run dirty, it holds visible fish and a long fly-fishing tradition.

Wading: Deep clear pools, slick pumice; crowded mouth — give anglers room
