Navigation beacons in Whangaroa and Kaipara Harbours are to be upgraded at a cost of about $17,000.
Jim Lyle, the Northland Regional Council's Opua-based Regional Harbourmaster, said upgrades and maintenance of navigation aids was vital.
The Whangaroa South Head light is an important coastal light providing guidance towards the narrowharbour entrance, as well as a red sector marking the Arrow Rocks, Mr Lyle said.
"The light was fitted after recommendations following a 1983 tragedy when seven people died after the yacht Lionheart foundered in a severe storm trying to find the entrance to the harbour.
"Sail Point light is just south of Ruawai. The shore-based light is positioned near the top of the huge harbour, giving some surety to navigators in an area where shifting sands make maintaining buoys and beacons difficult."
Mr Lyle said the existing sector lights at both the Kaipara's South Head and Sail Point are of an older style technology and have been operating for more than 20 years.
"Council's maritime team is about to upgrade them to new LED lights, which offer a number of advantages. They need less maintenance than the existing lights and deliver a much crisper and clearer light due to their advanced lens design."
The flash characteristic of the South Head light will be quickened from a 12 second cycle to a six second cycle but the sequence and sector directions will remain unchanged.
