About Waitarakao Washdyke Lagoon
Waitarakao is a shallow brackish coastal lagoon separated from the sea by a shingle barrier beach. It lies on the South Canterbury coastline north of Timaru and forms part of a threatened network of coastal wetlands. The lagoon and surrounding area hold significant ecological, geomorphological and cultural values, including as a mahinga kai site for Te Rūnanga o Arowhenua.
Historical records show the lagoon was substantially larger in the past. In 1881 it covered approximately 253 hectares. Drainage, land reclamation, changes to the catchment and the effects of the Timaru Port breakwater on sediment supply have reduced its size to less than 48 hectares today. The surrounding refuge area remains classified for wildlife protection.
Environment Canterbury leads the “Our Waitarakao” catchment strategy in partnership with the community, Timaru District Council and mana whenua. The project focuses on restoring lagoon health, improving water quality and protecting biodiversity and cultural values through coordinated catchment actions.
Birdlife and Birdwatching
The lagoon provides feeding and stopover habitat for migratory waders and supports a range of resident waterbirds throughout the year. Documented species include bar-tailed godwits, sandpipers, dotterels, oystercatchers, turnstones, herons and gulls. Dotterels nest on the eastern shingle barrier, while a nearby reef offers additional feeding areas for waders.
Birdwatching is the primary visitor activity. Binoculars are recommended because birds maintain a natural distance. Early morning visits and migration periods (typically September–October arrivals and February–March departures for godwits) offer the best viewing. The mix of open water, mudflats and shingle supports year-round diversity.
Access and Visiting
The site is reached via the Washdyke area north of Timaru. A new public accessway with a formed path and viewing seat opened in June 2024, providing improved coastal and lagoon views while protecting adjacent farmland. Walking along the lagoon edges offers vantage points for observation and photography.
Whitebaiting occurs at the lagoon’s sea connection during the season (typically August to November). Recreational fishing is permitted, though commercial fishing is prohibited. Visitors should respect the wildlife refuge status by avoiding disturbance to nesting birds and keeping dogs under control.
Restoration and Conservation
The “Our Waitarakao” project addresses ongoing pressures on the lagoon and catchment. Key partners are working on actions to improve habitat, water quality and community connection. Recent community engagement has informed a draft catchment strategy with implementation continuing.
What Visitors Often Say
Visitors describe the lagoon as a peaceful spot for birdwatching close to the city, with good opportunities to observe waders and waterfowl from the edges. The new access path and seat are appreciated for providing easier and more comfortable viewing.
Many note the contrast between the industrial surroundings and the wildlife refuge, finding it a quiet, low-key destination suitable for photography and relaxed walks, especially in the early morning.
