Our beaches are our favourite part of summer, but is there more danger under our feet than we thought? We dug out the data to see how you can prevent a summer injury stopping your fun.


Aotearoa loves a beach summer, but it turns out that feeling of sand beneath your toes can also bring unwanted injuries.

New figures show that over the past 10 years, there have been an average of almost 1400 claims each year for sand-related injuries in the six-week period between December 20 and January 31 (the period that roughly aligns with the summer school holidays).

These injuries have come at a cost of about $10.3 million, or $1.03m each year, to help people recover. The figures show soft tissue injuries like muscle strains, ligament tears, and bruises account for almost half (45%) of these injuries, with the ankle and knee the most common injured areas.

Cuts and stings account for 9% of injuries, while a small number of claims (about 4.5%) relate to sand getting in people’s eyes.

There were 1433 sand-related injuries in this six-week period in 2021-22, the second-highest in the past 10 years behind the 1446 claims recorded in 2018-19.

Last year’s cost of $1.4m to help people recover was the equal-highest in the past 10 years, along with 2018-19.

The data shows most injuries occur while people are walking and running or doing a sporting or recreation activity.

Running the risk

ACC Injury Prevention Leader James Whitaker says exercising and playing on the beach can lead to increased muscle and ligament fatigue because of the uneven and unstable nature of sand. This risk can increase if exercising barefoot because of the extra strain on muscles and ligaments.

“New Zealanders love getting down to the beach in the hot summer months to exercise, play sport, and spend time with family and friends,” James says.

“Whether it’s some beach cricket or football or just throwing a ball or frisbee around, the beach is a great place to be, and we love that Aotearoa gets out there amongst nature. But we also know that exercising on the beach poses unique injury risks because of the extra strain soft surfaces like sand can put on our muscles and joints.

“If we are not used to exercising on these surfaces, we can increase our chance of getting injured.”

Research shows 90% of all injuries are predictable and therefore preventable, and James says there are ways to stay safe while playing or exercising on the beach these holidays.

“If planning to run along the beach, spend time getting used to uneven surfaces by standing on gravel or running short distances on sand to begin with; avoid taking excessive strides; and don’t lean too far forward on your foot.

“For people heading to the beach for some sun and recreation, be aware of muscle fatigue, check the ground below you for uneven surfaces and foot holes, and avoid overdoing it because a lot of injuries can happen when we are tired and not concentrating.

“Be aware also that exercising barefoot will give you less support for your muscles and joints and can increase the chance of cuts from things like stones and seashells.

“We can’t wait to see everyone out there on the beach this summer, but we want everyone to stay safe so they can continue doing the things they love with their friends, family, and workmates.”
