Surf lifesavers at Muriwai Beach near Auckland have moved a patrol tower for the third time in 12 years because of beach erosion caused by last month's storms.
The tower was left dangling after the storms.
The series of severe weather events has shaved up to seven metres off dunes, with sea swells reaching six metres during one storm and pushing into a nearby carpark.
It costs about $25,000 to shift the tower because of the heavy machinery required and the need to buy new materials and place foundations.
The Muriwai Lifeguard chairperson Tim Jago says the weeks of storms were unprecedented but it will not be long before another shift will have to be made.
Mr Jago says the new site, several metres north, remains exposed and the service will be very lucky to have the tower last three years in its new location.
