Lake Matiri is a remote and scenic lake tucked deep within the Matiri Valley in the Nelson/Marlborough region of New Zealand's South Island, sitting within the broader Buller catchment. The lake is accessible via Matiri Valley Road, which branches off State Highway 6, and the journey into this backcountry destination reflects its wild, unspoiled character. The surrounding landscape is dominated by rugged terrain, dense native bush, and the kind of solitude that draws anglers seeking an authentic New Zealand wilderness experience. It is worth noting upfront that there are no trout in or above Lake Matiri itself — the productive trout fishing in this valley is found in the Matiri River below the lake rather than in the lake proper.
