The Waitahanui River mouth — where the Waitahanui River enters Lake Taupō on the eastern shore — is one of New Zealand’s most iconic fly fishing locations. Known simply as the rip, this is where anglers wade into the lake to cast flies into the current seam at the river mouth, targeting trout that congregate in the productive mixing zone of warm lake and cool river water. It is a short drive south of Taupō on SH1 and visible from the highway.

The Rip
The rip at the Waitahanui mouth is a classic Taupō lake mouth fishery. Where the Waitahanui’s current pushes out into the still water of the lake, a mixing zone forms — the current seam — and it is here that trout hold, feeding on whatever the river washes down. In summer, as the lake surface warms, trout move toward the cooler tributary water, and the mouths become more productive. In autumn, large brown trout move toward the river and concentrate near the mouth before ascending. In winter, rainbow trout heading upriver to spawn crowd the mouth.
The visual spectacle at the Waitahanui rip is part of its legend — anglers often stand in a line in the shallows, casting into the lake. The etiquette of sharing the rip (taking turns, giving space, moving through the line) is an established local tradition. It is a very visible, very social form of fishing that is quite unlike the solitary upstream river experience.

Frequently Asked Questions
What is the Waitahanui rip?
The point where the Waitahanui River meets Lake Taupō — a mixing zone of river current and lake water where trout congregate and anglers wade in to cast flies.
When is the best time to fish the Waitahanui rip?
Autumn (April–May) for large brown trout near the mouth, and winter (June–August) during the rainbow trout spawning run. Summer can also be productive as lake temperatures rise.
Can I use a spinner at the Waitahanui mouth?
No — fly fishing only is required within 200m of all Lake Taupō river mouths.
How close can a boat get to the Waitahanui mouth?
Boats must stay at least 200m from the Waitahanui mouth. Shore fishing (wading) is the only way to fish at the rip itself.
The Waitahanui rip is the best-known lake mouth in the Taupō fishery. For upstream river fishing, see the Waitahanui River fishing guide. The Taupō fishing hub covers all district options.
