Last updated July 2026
Nestled just south of Christchurch, Lake Ellesmere (Te Waihora) is Canterbury’s largest lake and a shallow coastal lagoon of major ecological and cultural importance. This brackish body of water, covering around 20,000 hectares, supports diverse fish and birdlife while serving as a key mahinga kai site for Ngāi Tahu. The lake has no natural outlet to the sea and requires artificial openings managed jointly by Environment Canterbury and Te Rūnanga o Ngāi Tahu. Visitors can enjoy recreational fishing for species such as flounder and eels, alongside opportunities for birdwatching in this internationally significant wetland. Respectful engagement with the lake’s heritage and ongoing restoration efforts is essential for all who visit.

About Lake Ellesmere (Te Waihora)
Te Waihora is a shallow, brackish coastal lagoon formed behind Kaitorete Spit. It is recognised as the largest lake in Waitaha/Canterbury and an internationally important wildlife habitat. The lake supports a wide range of native and introduced fish species as well as significant wetland bird populations.
Traditionally known as Te Kete Ika o Rākaihautū (the fish basket of Rākaihautū), the lake has long been a vital source of mahinga kai for Ngāi Tahu. Archaeological evidence, including the oldest Māori cloak found in Aotearoa, underscores its deep cultural and historical significance. The lake bed was returned to Te Rūnanga o Ngāi Tahu under the 1998 Ngāi Tahu Claims Settlement, affirming its status as a tribal taonga.
Today the lake faces water quality challenges from historical land use and agricultural runoff. Major restoration initiatives, including Whakaora Te Waihora, aim to improve ecosystem health while maintaining cultural values. Co-governance arrangements ensure Ngāi Tahu perspectives guide management decisions alongside environmental priorities.
Visitors experience a remote, windswept landscape ideal for quiet recreation. The area offers excellent birdwatching and fishing opportunities when conditions allow, though facilities remain basic and visitors should prepare for variable weather and muddy terrain.
Fishing at Te Waihora
Recreational fishing at Te Waihora includes targeting pātiki (flounder), tuna (eels), brown trout, perch and whitebait when the lake is open to the sea. Good numbers of sea-run trout can appear in the lower reaches of inflowing rivers during open periods. Primary fishing locations include the Selwyn River mouth, Harts Creek, Huritini/Halswell River, Irwell River, Kaituna River and areas near the lake opening.
Ngāi Tahu have designated some zones for customary and recreational fishing only. Fisheries regulations restrict net use at river mouths and specify permitted gear types. Customary fishing permits are administered by Tangata Tiaki. Always check current rules and lake opening status before fishing, as water levels and access can change rapidly.
Cultural Significance
Te Waihora holds outstanding significance for Ngāi Tahu as a tribal taonga and historic mahinga kai site. Generations have gathered resources such as eels and flounder from its waters and margins. The return of lake bed ownership in 1998 reinforced iwi rangatiratanga over this important cultural and food-gathering area.
Co-governance with Environment Canterbury ensures cultural protocols and restoration priorities shape lake management. Visitors are encouraged to respect these values and the lake’s role in Ngāi Tahu identity.
Environmental Management and Access
Because Te Waihora has no natural outlet, Environment Canterbury manages artificial openings through Kaitorete Spit near Taumutu. These openings support fish passage, control water levels and reduce flooding risk to surrounding farmland. Opening decisions involve a protocol group that includes Te Taumutu Rūnanga, the Department of Conservation and other stakeholders.
Public access is available at several points, particularly around Taumutu. Roads are generally well maintained, and the drive from Christchurch via State Highway 75 takes about 45 minutes. Parking and boat ramps exist at limited locations, but on-site facilities are minimal. Nearby Leeston provides basic supplies. Visitors should check current lake levels and opening status on the Environment Canterbury website before travel.
What Visitors Often Say

Birdwatchers highlight the impressive variety of wetland species and the expansive views across the lagoon. Reviewers often mention the need to be prepared for wind, mud and changing water levels, and they value the quiet, undeveloped character of the area.
