Groundswell Sports is a specialist shop at Unit 2, 1030 Ferry Road in Woolston, Christchurch, for windsurfing, kitesurfing, wing foiling and paddleboarding. The website calls it New Zealand's home for foiling, windsurfing, kiteboarding and SUP. The shop stocks boards, wings, sails, foils, wetsuits, vests, harnesses, parts and accessories from brands including Duotone, Cabrinha, Neil Pryde and XSURF. The website describes Foil Drive, which electrifies any mast, and says last season's gear is up to 50% off, as at 2026. Gear can be hired, according to reviewers, and the website offers nationwide shipping.
The website says the staff ride the gear they sell, and that the business has been there since the early 1980s. Reviewers praise the expert advice. One visitor from Scotland hired gear and was given tips on a spot at Lyttelton. Another reviewer says a harness sold for converting to kiteboarding was rigged incorrectly.
