"Disturbing" behaviour from jet ski riders in Hawke's Bay has water safety officials fearing a serious incident.
Coastguard Hawke's Bay skipper Henry van Tuel said they'd had multiple reports in the past few days of jet-skiers "zig-zagging" within 200m of shore.
"A person is a really small target in the water and if people are not looking out for swimmers, it is really easy to run them over."
Van Tuel said the impact of a jet ski on a swimmer could be similar to a pedestrian being hit by a motorbike or even a car, and could result in serious injury.
Hawke's Bay Regional harbourmaster Captain Martin Moore said watercraft users often didn't realise there was a five-knot speed rule when travelling within 50m of another vehicle, 200m of one showing a dive flag and 200m of the shore, unless it is otherwise lifted.
