Grovetown is a small rural village on the Wairau Plain a few kilometres north of central Blenheim, sitting between State Highway 1 and the Wairau River. It’s a quiet residential settlement of just over 200 households, best known to visitors for the adjacent Grovetown Lagoon — an oxbow lake created when the Wairau River changed its course about 155 years ago. The lagoon has a 3.8 km loop walking track, a birdwatching hide, and is a notable wetland habitat. The village itself has a primary school and basic amenities.

About Grovetown
Grovetown is one of the small Wairau Plain settlements that sit on the flat land north of Blenheim. The village character is rural-residential — a working country settlement rather than a destination village, with primary school, residential streets and direct access to the Wairau River. The village’s name lives on most prominently through Grovetown Lagoon — the oxbow lake that was created when the Wairau River cut a new course around 155 years ago, leaving the curved former channel as a standalone water body.
Grovetown Lagoon is now the main visitor draw for the area: a 3.8 km loop walking track runs around the lagoon edge through wetland habitat, with a birdwatching hide partway around and a kayak launch on the south-western side. The lagoon supports New Zealand Scaup, Grey Teal, Australasian Shoveler, Royal Spoonbill, Black Swan, Pūkeko and a variety of shag species — early mornings and late afternoons in spring and summer are the best birdwatching times.
