Hokitika River

The Hokitika River mouth flowing into the Tasman Sea on New Zealand's West Coast

The Hokitika is a fast, scenic West Coast river holding strong brown trout — but it lives by the weather and its glacier-fed headwaters, so it can run milky and rises hard after rain.

The nearest gauge doesn't record temperatures, so we've estimated it — defer to the river keeper's advice.

How these readings are sourced

Weather-only: no live gauge wired. Spate river with glacier-fed headwaters — read both rain colour and glacial tinge plus flow trend. Stale data is dangerous.

About this water

Time it to the falling, clearing flow, and lean on the clearer lower reaches and tributaries when the main river is up. Big, powerful water to wade with care.

Under the surface

The Hokitika races out of the Southern Alps through gorge and rainforest to the West Coast town that bears its name, a fast, beautiful river of greenstone-clear water that can turn milky with glacial melt and rises hard after rain. Strong brown trout hold its runs and the clearer reaches in high-rainfall wilderness country.

Wading: Fast pushy water, glacial colour, fast rises — serious wading care

Hatches & food

Green beetles and cicadas carry the terrestrial season on the middle and upper river in the same pattern as neighbouring West Coast rivers, while September to December brings sea-run trout into the lower tidal reach chasing the whitebait run — a prey event rather than a hatch, and lower-river only.
