About Grovetown
Grovetown sits on the flat Wairau Plain north of Blenheim and functions as a working rural-residential community. Residents value the combination of countryside living with quick access to town amenities and green spaces. The settlement includes residential streets, a primary school that acts as a local hub, and direct proximity to the Wairau River.
The village takes its name from the surrounding area and is most visible to visitors through its connection to Grovetown Lagoon. This oxbow lake formed when the Wairau River cut off a bend, creating a standalone wetland feature. The lagoon and surrounding areas hold cultural significance as mahinga kai for local iwi, who have partnered in restoration work since 2002.
Restoration efforts by the Grovetown Lagoon Restoration Project involve Marlborough District Council, iwi groups including Te Rūnanga a Rangitāne o Wairau, Ngāti Rārua and Ngāti Toarangatira, the Department of Conservation and the community. The project focuses on enhancing natural values in this one of the larger remaining wetland areas on the Wairau Plain.
Grovetown Lagoon
Grovetown Lagoon is a remnant oxbow lake beside the Wairau River, four kilometres northeast of Blenheim. It provides open water, swampy ground and springs that support diverse wetland habitat. The site is popular for walking, birdwatching, picnicking and kayaking.
A circuit track runs around the lagoon, with a birdwatching hide accessible along the route. Picnic tables are located near the hide and beside the river. Kayaks can be launched from the south-western side of the lagoon. Early mornings and late afternoons offer good opportunities to observe birdlife.
Birds commonly seen include pūkeko, grey teal, Australasian shoveler, black swan, shags and paradise shelduck. The lagoon remains a focus for ongoing habitat enhancement and community involvement.
Walking and Access
The main walking option is the easy, flat circuit around the lagoon, suitable for most visitors and taking around 55 minutes on foot. The track passes through wetland areas and offers views of the water and surrounding vegetation. Bikes are permitted and dogs must be kept on a leash.
Access is from Blenheim by turning off State Highway 1 at Grovetown onto Fell Street, then continuing to Steam Wharf Road. Parking is available at the end of Steam Wharf Road, with paths leading to the lagoon and river stopbank areas. The site is open at all times with no entry fees.
