About the Wairau Lagoons Walkway

The Wairau Lagoons formed over the last 6,500 years behind an 8 km boulder bank. They create a protected estuarine environment of shallow saline lagoons where the Wairau River meets the sea. The lagoons provide nutrient-rich feeding habitat for wading birds, shorebirds and waterfowl. The walkway gives insight into this productive wetland ecosystem and its specialised plants and animals.

The track is virtually flat and easy underfoot in dry conditions. After heavy rain some sections near the lagoon edge can become soft. Visitors should bring binoculars as much bird activity occurs on open water and mudflats at a distance. Hot dry conditions and strong cold winds are common in the area.

The lagoons have long supported human activity. Māori hunted for food here and some channels may have been extended to trap moulting birds or eels. Early camps on the boulder bank show evidence of moa hunting.

Walking the Track

The loop starts from the carpark at the end of Hardings Road. It follows the shoreline of the upper lagoon past Budges and Moerepo Islands to the main channel. Walkers can return the same way or take a more direct route across the saltmarsh with its salt-resistant plants. It is also possible to continue beyond the Waverley for views of the river. The track is ideal for children who can manage the distance.

Birdwatching at the Lagoons

Almost 90 bird species have been recorded at the Wairau Lagoons, making it one of the most biodiverse wetland sites in the South Island. The royal spoonbill (kōtuku ngutupapa) is a highlight species, with a breeding colony established here since 1979. Other regularly seen species include pied stilt, South Island pied oystercatcher, banded dotterel, white-fronted tern, grey teal, New Zealand shoveler and paradise shelduck. Early morning visits and low tide conditions offer the best viewing.

The Waverley Wreck

The TSS Waverley is a 19th-century steamer built in 1883. It was towed from Wellington to be scuttled as a breakwater at the Wairau River mouth. A flood swept the vessel up the channel to its current resting place in the lagoons where it has slowly rusted for decades. The hulk is a distinctive landmark and popular photography subject, especially at low tide.

What Visitors Often Say

Walkers describe the track as an easy and rewarding outing with abundant birdlife and the striking sight of the old shipwreck. Many note that binoculars are essential and recommend visiting at low tide or early in the day for the best experience.

Birdwatchers highlight the lagoons as a reliable site for royal spoonbills and a variety of estuarine species, often comparing it favourably to other South Island wetlands for accessibility and diversity.
