Police were notified at about 3.40 this afternoon of a person appearing to be in trouble in the water off Cliff Road, St Heliers.
The person was safely removed from the water.
Saturday's multiple rescues were "a timely reminder of the dangers of the surf environment and how quickly conditions can change", a spokesperson for Surf Life Saving Northern said in a statement.
"The message from all patrol captains today was the importance of swimming in between the flags, especially in treacherous west coast conditions."
Meanwhile, Hamilton police are urging the public to use common sense if they are heading into the water this weekend, after being called to multiple rescues in the Waikato River in recent days.
Hamilton City Area Commander Inspector Andrea McBeth said while the river may be a tempting spot for a quick swim, it has fast flowing and changeable currents, with whirlpools in some parts.
McBeth said to ensure safety, it's important to be prepared - know the water and weather conditions before you get in, and always swim with others.
