Mavora Lakes

Mavora Lakes Conservation Park protects an impressive landscape of mountains, lakes, beech forest, and tussock grassland in the Southland region of New Zealand's South Island, approximately 60 kilometres northwest of Te Anau. The park encompasses the twin glacial lakes of North Mavora and South Mavora, set within a dramatic valley framed by the Livingstone and Thomson mountain ranges. Recognised as part of the Te Wahipounamu South-West New Zealand World Heritage Area, Mavora Lakes gained international fame as a filming location for Peter Jackson's Lord of the Rings trilogy, representing scenes of Nen Hithoel, the Silverlode and Anduin rivers, Fangorn Forest edge, and landscapes south of Rivendell.

Mavora Lakes Conservation Park provides critical habitat for numerous native bird species within its diverse forest and wetland ecosystems. The beech forests shelter populations of the South Island robin, bellbird, grey warbler, and fantail, while the rare karearea (New Zealand falcon) hunts across the open tussocklands and forest margins. The fast-flowing rivers and streams support populations of whio (blue duck), one of New Zealand's most endangered waterfowl species that requires pristine waterways free from introduced predators. The lakes themselves contain healthy populations of native longfin eels and provide habitat for numerous invertebrate species, while the surrounding wetlands support native fish species including koaro and bully.

The park's vegetation reflects the transition between the wetter western regions and drier eastern environments, creating distinct ecological zones throughout the conservation area. Silver beech and mountain beech forests dominate the valley floors and lower slopes, with mature trees draped in mosses and lichens creating a primeval atmosphere that made the area ideal for fantasy film locations. Above the treeline, extensive alpine tussock grasslands cover the valley floors and lower ridges, interspersed with native shrubs including matagouri, coprosma, and hebe species. Wetland areas around the lake margins support carex sedgelands and native rushes, while the forest understorey contains diverse ferns, mosses, and flowering plants adapted to the cool, moist environment.

The Mavora Lakes were carved by glaciers during the Pleistocene ice ages, with massive ice flows scouring the valley floors to create the elongated lake basins that characterise the landscape today. The surrounding mountains consist primarily of greywacke and argillite sedimentary rocks that were uplifted and folded during the formation of the Southern Alps, creating the rugged peaks of the Livingstone and Thomson ranges. Terminal moraines deposited at the southern ends of both lakes mark the furthest extent of glacial advance, forming natural dams that impound the waters. The landscape continues to be shaped by erosion and frost action, with distinctive scree slopes and exposed rock faces visible on the higher peaks surrounding the valley.

Mavora Lakes Conservation Park experiences a temperate oceanic climate with cool temperatures year-round and significant seasonal variation in conditions. The park's location in the rain shadow of the Fiordland mountains results in lower rainfall than the West Coast, though precipitation remains substantial with regular frontal systems bringing wet weather from the Tasman Sea. Winter temperatures frequently drop below freezing, bringing snow to the surrounding peaks and occasional dustings to the valley floor, while summer daytime temperatures typically reach the mid-teens to low twenties Celsius. Weather conditions can change rapidly in this mountainous environment, and visitors should be prepared for cold, wet conditions at any time of year.

The Mavora Lakes area holds significant cultural importance for Ngai Tahu, whose ancestors used the valley as a seasonal travel route connecting the interior with coastal settlements for centuries before European arrival. The lakes are formally recognised under the Ngai Tahu Claims Settlement Act, acknowledging their association with iwi groups including the Hokonui Runanga and their traditional significance for mahinga kai (food gathering). European settlers established pastoral runs in the area during the mid-nineteenth century, grazing sheep and cattle on the tussock grasslands that still characterise much of the landscape. The isolation and rugged beauty of the area kept it relatively undeveloped, preserving the wilderness character that would later attract international film productions and modern recreational users.

Mavora Lakes Conservation Park was established to protect the outstanding natural and scenic values of this remote Southland valley, recognising its ecological significance as part of the broader Te Wahipounamu World Heritage Area. The Department of Conservation now manages the park, balancing recreational access with protection of the sensitive ecosystems and cultural heritage values. The area gained international prominence when Peter Jackson's production team selected Mavora Lakes as a filming location for the Lord of the Rings trilogy between 1999 and 2000, with scenes filmed here appearing in all three films released between 2001 and 2003. The films significantly boosted visitor numbers to rural Southland sites like Mavora Lakes, with approximately one in five overseas visitors to New Zealand citing the Lord of the Rings films as a reason for visiting by 2019.

The Mavora-Greenstone Walkway is the park's premier tramping route, a 50-kilometre four-day journey linking the Mavora Lakes camping area with the Greenstone Track through open valley tussockland and beech-forested hill country. Shorter walks around North Mavora Lake offer accessible options for day visitors, with trails passing through atmospheric beech forest and along lakeside beaches that featured in the Lord of the Rings films. The lakes themselves provide excellent opportunities for trout fishing, with brown and rainbow trout attracting anglers from throughout New Zealand and internationally. Hunting for red deer and pigs is permitted in designated areas, while the surrounding valleys and ridges offer challenging routes for experienced trampers seeking backcountry adventure.

Access to Mavora Lakes Conservation Park is via the Mavora Lakes Road, an unsealed route that branches from the Te Anau-Mossburn highway and travels through farmland before entering the park boundary. The Department of Conservation operates basic campgrounds at both North and South Mavora lakes, offering toilet facilities and lake access but no powered sites or showers. The road can become challenging in wet conditions and may be impassable after heavy rain or snow, so visitors should check conditions before travelling. Four-wheel drive vehicles are recommended, particularly in winter or after wet weather, and campervans and caravans should exercise caution on the narrow, winding access road.

Mavora Lakes Conservation Park plays an important role in protecting representative examples of eastern Fiordland ecosystems within the Te Wahipounamu World Heritage Area, one of the largest and least-modified natural areas in the temperate zone. Ongoing predator control programmes target introduced stoats, possums, and rats that threaten native bird populations, with particular focus on protecting whio (blue duck) breeding sites along the park's rivers and streams. The park's remote location helps maintain relatively low pest densities compared to more accessible areas, though vigilance remains necessary to prevent new invasions. Conservation managers balance increasing visitor interest, particularly from Lord of the Rings tourism, with protection of fragile ecosystems through careful track maintenance, camping area management, and visitor education programmes.
