"We're getting really encouraging results in a relatively short time – more kiwi and other native wildlife are returning to places where people are working collectively on pest control," he said.
"There's a lot of hard work going on at grass roots level right around the region, and it's great to see the positive results coming through."
Among the initiatives Mr McElrea introduced, or is part of, are Whangārei Predator Free, the Kiwi Coast/NRC Partnership, Tiakina Whangārei and Project Pest Control.
Council chairwoman Penny Smart says it was great to see staff recognised for their work in biosecurity, which was a vital part of the authority's work on behalf of the community.
"We have a very talented team working in this area, where a number of national awards have been won for innovative initiatives introduced in recent years," she said.
"This is such important work, and I'd like to thank all the people voluntarily engaged in the battle to protect our environment from biological threats, including invasive animal and plant pests and diseases. We couldn't do what we do without you."
