"Everyone was very upset when the attack happened. The community rallied together. The council rallied together, the work has been done and to add to that there are more volunteers manning the screens at the police station. It's a case of the community pulling together so everyone knows the loop is a safe place," he said.
Mr Thomas said $100,000 went towards CCTV cameras.
He said the growth to the network meant the hardware at the police station, where the cameras were monitored, also had to be altered.
The cost of the lighting was $300,000.
Work on lighting the Pohe Island side of the loop was delayed by an old dump site in the area releasing potentially explosive methane gas.
Mr Thomas said those issues had been addressed.
