Phase 2 would be development of a monitoring and/or GPS tracking system to notify emergency services when a device was removed, and the installation of more tubes around Doubtless Bay.
Phase 3 would be collaboration with other communities to replicate the system throughout the Far North once the concept had been refined and agreed.
Doubtless Bay had wasted no time in acquiring equipment that might well save lives after Renata died, Millar making a start by attaching a fishing float to a tree on the beach at Cable Bay.
"All the news reports say if anyone is in trouble, first call for help, then, if you go to assist, make sure you have a flotation aid. Hence the float, left over from when my husband had a fishing boat," she said at the time.
"One of my friends said they would contribute to a proper rescue aid. When I found out it cost over $200 I texted seven other friends and asked them if they wanted to contribute, and suddenly I had more than enough."
In 2018 the price of each tube was $255, delivered (from the US) and marked with information regarding their use and what to do in an emergency in both English and te reo. By August 2018 tubes had been installed at Cable Bay, Taipa (opposite the resort) and Cooper's Beach (at the carpark and outside the San Marino Motel).
