About the Waiau River
The Waiau River is Southland’s largest river. It begins as the outflow of Lake Te Anau, flows 10 km south into Lake Manapouri, and then continues approximately 70 km to Foveaux Strait near Tuatapere. The upper section passes through Fiordland National Park, where forested banks and mountain backdrops create a striking setting.
Hydroelectric development at the Manapōuri Power Station has significantly reduced the river’s natural flow downstream of Lake Manapouri. Despite the altered regime, the river remains an important waterway supporting recreational fishing and local ecosystems.
Visitors reach the most popular fishing and scenic areas via the Te Anau–Manapouri road. The proximity to Invercargill allows for straightforward day trips, while the surrounding national park offers additional opportunities for longer exploration on foot or by kayak.
Fishing on the Waiau River
The upper Waiau River between Lakes Te Anau and Manapouri is recognised for its high density of trout. Both brown and rainbow trout are present, and the river is the only one in Southland where anglers may also target chinook salmon during the open season. Fish & Game surveys note productive late-summer evening rises, particularly during caddis hatches. Regulations, bag limits and access details are published annually by Fish & Game Southland.
Recreation, Walking and Access
Beyond fishing, the river corridor supports kayaking on calmer stretches and short walks along tracks such as sections of the Kepler Track. A swing bridge near Rainbow Reach provides easy river views. The area is suitable for picnics and scenic drives, with public access points signposted from the main highway. Visitors should check current track and weather conditions before heading out.
Cultural and Historical Context
The name Waiau derives from Māori words meaning “swirling waters” or “river of swirling currents.” The river holds cultural significance for local iwi as a traditional resource and travel route. European-era hydroelectric development changed its flow regime, yet the waterway continues to feature in regional heritage and storytelling.
Filming Location
Parts of the Waiau River between Te Anau and Manapouri were used as the River Anduin in The Lord of the Rings trilogy. The forested banks and surrounding peaks provided the backdrop for several scenes, adding cinematic interest for fans exploring the area.
What Visitors Often Say
Anglers praise the upper reaches for consistent trout action and scenic beauty, noting productive evening rises in summer. Many describe the drive from Invercargill as straightforward and the riverbanks as peaceful for relaxed fishing or short walks.
Visitors highlight the dramatic Fiordland setting and the chance to combine fishing with easy riverside strolls. Some mention the LOTR connection as an added draw when planning a day trip.
