The Waihaha River mouth is where the Waihaha River enters the western shore of Lake Taupō, forming a delta and rip fishery that is among the more remote and least-pressured in the Taupō district. Like the other productive lake mouths — the Waitahanui, Hinemaiaia, Tauranga-Taupō, and Kuratau — the Waihaha mouth creates a mixing zone of cool river water and warmer lake water where trout concentrate, particularly in the summer months and during the autumn and winter run seasons. All fishing is within the Taupō Trout Fishery, requiring a special DOC licence.
Practical Information
| Location | Western shore of Lake Taupō, approximately 20 km north of Kuratau |
| Licence required | Yes — Taupō special licence from DOC |
| Method | Fly fishing only within 200m of the river mouth |
| Fish species | Rainbow trout; brown trout |
| Best time | Twilight and dusk — trout feed most actively at the delta in fading light |
| Best season | Summer (lake warms, fish seek tributary flows); autumn for brown trout staging |
| Access | Boat access from Taupō or western shore; road access to the western shore is limited |
| Guided trips | Charter fishing operators offer guided trips to the Waihaha delta from Taupō |
The Mouth and Delta Fishery
The Waihaha River forms a delta where it meets the lake — a shallow zone of braided channels and current seams where the river’s cooler, oxygenated water mixes with the warmer lake. Trout use this transition zone as feeding ground, cruising the delta edges and current seams in search of food washed down from the river system. The evening and twilight hours are consistently the most productive at the Waihaha mouth, with fish moving into the shallows as the light fades.
Fly fishing the delta typically means wading thigh-deep at the current seam, casting into the mixing zone. The technique is similar to other Taupō lake mouth rips — reading the water to find where the river current meets the still lake, then presenting a fly into the zone where trout are holding. The Waihaha delta’s shallowness means fish can be spotted cruising, which adds a sight-fishing element not always available at other mouths.
Access and Remoteness
The western shore of Lake Taupō is not accessible by road for most of its length. The Waihaha mouth is approximately 20 km north of Kuratau — the nearest western shore settlement — and reaching it by road involves a long drive around the lake. Boat access from Taupō is the most practical approach, with the Waihaha approximately 30–45 minutes by boat from the Taupō foreshore depending on conditions. The western shore’s remoteness is a genuine advantage: far fewer anglers reach these western mouths, and the fish here experience considerably less pressure than those at the easily accessible eastern shore rips on SH1.
Charter fishing operators run guided trips to the Waihaha delta — a worthwhile option for a first visit, as knowledge of the delta’s layout, best channels, and trout movement patterns makes a real difference to results.

Frequently Asked Questions
Where is the Waihaha River mouth?
On the western shore of Lake Taupō, approximately 20 km north of Kuratau. Boat access from Taupō is the most practical way to reach it — road access to this part of the western shore is very limited.
When is the best time to fish the Waihaha mouth?
Dusk and twilight are consistently the most productive. Seasonally, summer is best as lake temperatures rise and trout seek cooler tributary water, with autumn also productive for brown trout staging near the mouth.
Is fly fishing required at the Waihaha mouth?
Yes — fly fishing only within 200m of all Lake Taupō river and stream mouths. This applies whether fishing from the shore, wading, or from an anchored boat.
How do I get a Taupō fishing licence?
Online at the DOC website, from DOC offices in Taupō, or through licensed vendors in the town. The Taupō licence is specific to the Taupō Fishing District and is separate from a standard New Zealand Fish and Game licence.
Are there guided trips to the Waihaha?
Yes — charter fishing operators based in Taupō offer guided trips to the Waihaha delta, including Mr Fishing who specialise in Taupō lake mouth and delta fishing.
The Waihaha mouth is one of the western shore fishing options on Lake Taupō. See the Waihaha River fishing guide for the upstream river, and the Taupō fishing hub for all district options.
