Explosives may be used to blow up a reef deemed a navigational hazard for boaties using a popular launch ramp at Kerikeri's Waipapa Landing.
Northland Regional councillor Dover Samuels, harbour master Jim Lyle and council staff inspected the reef earlier this month following a series of complaints from boaties saying they had damaged or lost their propellers.
The reef was marked but, because it was immediately in front of the boat ramp, it was not easy to avoid. At low tide, it almost breached the surface, Mr Samuels said.
The ramp could not be shifted and an underwater inspection, including by Mr Samuels in his snorkel gear, had shown the reef was solid basalt and not loose rocks that could be removed by machine.
Mr Samuels said he backed the plan to blow up the reef as long as he could be assured properties around the landing would not be affected and nearby residents would be notified.
