How these readings are sourced

Weather-only: no live gauge wired. Snow-influenced in spring; sight-fishing best on clear, stable, low water with good light.

About this water

The Ahuriri is the Mackenzie sight-fisher's river — a clear, braided high-country stream running through tussock basins to Lake Benmore, holding large brown and rainbow trout you spot and stalk in gin-clear water. The upper river runs through conservation land and rewards stealth, good light and accurate casting over numbers. A spectacular, exposed high-country fishery; watch the weather and tread lightly.

Under the surface

The Ahuriri winds out of the high Mackenzie country through golden tussock basins toward Lake Benmore, a clear, braided high-country river under big skies and bigger mountains. Its upper conservation-park reaches are classic South Island sight-fishing water — large browns and rainbows holding visible in gin-clear flats and runs.

Wading: Clear water spooks fish; cold snowmelt, exposed high country — stealth and weather care
