About Hinemaiaia River

The Hinemaiaia is a small river that runs into the eastern side of Lake Taupō at Hatepe. It drains a lake that is part of a hydro scheme, so its flow is steady and stays clear even after long rain, when the bigger rivers are high. The valley is regenerating native bush, with community pest control bringing the birds back. It fishes well for large spawning rainbows in winter and gives pleasant dry-fly fishing in summer. It is fly fishing only below the dams, under DOC's Taupō licence.

It is small, but it is full of snags, so accurate casting pays and big fish are hard to hold. Many anglers use an 8 weight in early winter when the larger rainbows run, even though the river would suit lighter gear. Nymphing is the usual method, and a wet fly can reach fish in places a nymph cannot. In a good season the run rainbows average over 50 cm and 1.7 kg, and most anglers fish between the State Highway 1 bridge and the Cliff Pool.

Car parks link to tracks along the river. The mouth and lower river are off State Highway 1 at Hatepe, and the upper river is reached by the access road to the Hinemaiaia dam. Above a sign about halfway between the highway bridge and the lower (HB) dam, the river opens only from 1 December to 31 May, and fishing stops 300 m below the powerhouse. The flow is steady, but the dam can spill and send a surge down after prolonged heavy rain. The banks are high in places, with steep steps.

Sections

2 reaches

Mouth to the halfway sign

WadeRainbow Trout

From the mouth at Hatepe, under the State Highway 1 bridge and up through the bush to a sign about halfway between the bridge and the lower (HB) dam. Most anglers fish between the bridge and the Cliff Pool. Small, clear and full of snags, with high banks and steep steps on the tracks. Open all year, fly fishing only. The mouth has a changeable pumice drop-off.

Best for: Large spawning rainbow trout on nymphs in winter, often on an 8 weight to keep them out of the snags

Halfway sign to below the powerhouse

WadeRainbow Trout

The upper reach, from the halfway sign to a sign about 300 m below the powerhouse, reached by the access road to the Hinemaiaia dam. Open only from 1 December to 31 May, so this is summer water. Fishing is prohibited from there up to the lower dam.

Best for: Rainbow trout on dry flies and nymphs in summer, in a quiet bush valley

Best seasons

The lower river is open all year. Above the halfway sign, 1 December to 31 May. No gauge on this page reports the Hinemaiaia, so judge it by eye: these flows are rough limits, not readings. The hydro scheme holds it steady, usually about 1.5 to 5 m³/s (50 to 175 cfs) and clear. Only when the dam spills after prolonged heavy rain, above about 10 m³/s (350 cfs), does it surge and colour. It is a good choice after rain. Rainbows run through winter, and summer suits a dry fly.

Regulations

Fly fishing only below the dams. Open all year from Lake Taupō to a sign about halfway between the State Highway 1 bridge and the lower (HB) dam, and 1 December to 31 May above it, up to a sign about 300 m below the powerhouse. No fishing from there to the lower dam. Bag limit 8 trout, minimum 35 cm. A Taupō licence from DOC is needed.

Licence
A Taupō fishing licence from the Department of Conservation, valid 1 July to 30 June, bought online as a 24-hour, week, season or family licence. It is separate from the Fish & Game licence and does not cover Fish & Game waters. It gives the licence holder foot access over the designated lakeshore and riverbank rights of way, but not over other private land.

  • From 300 m below the powerhouse to the lower dam: fishing prohibited.
