Hamurana Stream Fishing: Trout at the Lake Rotorua Mouth

Last updated October 2026

The Hamurana Stream runs about a kilometre from Hamurana Springs, the deepest natural spring in the North Island, to the northern shore of Lake Rotorua. The spring holds at around 10°C all year, and in summer, when the lake warms, trout gather in big numbers in the cold plume off the stream mouth.

Only the stream below the Hamurana Road Bridge and the lake around the mouth can be fished: the stream above the bridge is closed to all fishing. A council reserve beside Hamurana Road gives easy access, with toilets and a boat ramp.

More About Hamurana Stream

Hamurana Springs pours out about 4 million litres an hour of cold, clear water, and the main spring is around 15 metres deep. It is a cold spring, not a geothermal one. The stream flows about a kilometre through the springs reserve to the lake, where it meets a shallow sandy shore.

Ownership of the springs returned to Ngāti Rangiwewehi under their Treaty settlement, and the springs are a paid-entry nature reserve with a loop walk through redwood and native trees. You can often see large rainbow trout in the clear water there in summer, but fishing is not allowed above the road bridge.

On the lakeshore, the council reserve runs along Hamurana Road with parking bays, a narrow beach and the golf course on the inland side, as the aerial photo shows. In hot summers, when the lake surface reaches the mid-20s, Fish & Game has described anglers standing shoulder to shoulder at the mouth, mostly catching rainbows with a few browns.

How to Fish the Hamurana Stream Mouth

Reading the plume

The cold stream water pushes out into the lake as a smooth plume. Fish & Game’s January 2026 report advises fishing both sides of it: rainbows tend to sit in the main flow, while browns lie off to the side waiting to ambush a bully or sip a damselfly nymph.

The mouth fishes well when the wind is not from the south; a southerly makes casting harder, although the fish are still there.

When to go

Summer is the main season, when trout leave the warm lake for the cold water at the mouths. The lake is shallow here, wading is easy and the mouth suits children and beginners. Expect company on hot days.

What to use

• Fly: bully patterns and damselfly nymphs for browns at the edge of the plume; Fish & Game also suggests Grey Ghost smelt flies at the Rotorua mouths.
• Spin: Fish & Game suggests a Black and Gold Toby at the Rotorua stream mouths.

Getting There and Facilities

• Driving: follow Hamurana Road around the northern side of Lake Rotorua. The council reserve sits between the road and the lake.

• Other users: guided paddle tours run on the stream, so give them room.
