Born from wind, waves, and innovation — Groundswell Sports is New Zealand’s original home of kiteboarding.

Originally known as Sailboards Underground and the birthplace of Underground Kiteboards, our roots run deep in the local and global wind sports scene. We were there at the start — pioneering the sport of kitesurfing in NZ and helping it grow from backyard experiments to world-class performance gear.

Today, Groundswell Sports continues that legacy with a curated selection of the best gear in kiteboarding, wingfoiling, windsurfing, and prone foiling — from the most trusted global brands to insider-favourite accessories. Based in the South Island, we’re proud to be NZ’s leading destination for wind and water sports.

Whether you're chasing your first downwinder, carving waves on a foil, or upgrading to the latest high-aspect wing — we're here to get you riding, flying, and frothing.
