The Wairau Lagoons Walkway is a 9 km DOC-managed loop through the estuarine lagoons east of Blenheim — one of the best birdwatching sites in Marlborough and one of the most reliable places in New Zealand to see royal spoonbills (kōtuku ngutupapa) in numbers. The flat loop track follows the upper lagoon shoreline, passing Budge and Moerepo Islands before reaching the rusting hulk of the historic Waverley in the lagoon’s main channel. The full loop takes around three hours to walk.

About the Walkway
The Wairau Lagoons is a protected estuarine environment — a network of saline lagoons formed where the Wairau River meets the sea. The lagoons are shallow and nutrient-rich, providing ideal feeding habitat for wading birds, shorebirds, and waterfowl. The walkway traverses the edge of the upper lagoon and takes in two distinct sections: the northern shore trail past the islands, and the main channel route where the Waverley sits.
The path is virtually flat throughout and easy underfoot in dry conditions. After heavy rain, some sections near the lagoon edge can be soft. Bring binoculars — a lot of the bird activity happens on open water and mud flats where distance matters.
The Waverley is a 19th-century schooner that was beached in the lagoon and has been slowly rusting in the channel for decades. It’s a distinctive landmark at the far end of the loop and a popular photography subject, particularly at low tide when the hull is more exposed.
Birds of the Wairau Lagoons
Over 70 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 the headline species — a large, striking white wading bird that feeds by sweeping its spatula-shaped bill through shallow water. The lagoons hold one of the country’s most reliable royal spoonbill populations and attract birding visitors from around New Zealand and internationally.
Other regularly recorded species include pied stilt (poaka), South Island pied oystercatcher (tōrea), banded dotterel (pohowera), white-fronted tern (tara), and a range of waterfowl including grey teal, New Zealand shoveler (kuruwhengi), and paradise shelduck (pūtangitangi).
