Staff members at the Far North District Council and Top Energy are among the Northlanders who have been diagnosed with the Covid-19 virus.
Mayor John Carter told a council meeting conducted by videoconference that the staff member had gone into isolation after being found to have Covid-19 about two weeks ago. Before developing symptoms they had "done a little bit of shopping etc., so that is an issue for us," he said.
Mr Carter would not say what the employee's role was, but said the public had not been put at risk through dealings with the council.
He added that Far North lines company Top Energy and contracting company Broadspectrum also had workers who had tested positive. A case of Covid-19 at New World in Kaikohe had already been widely reported in the media.
"The point I'm making is that it's in our community, it's amongst us, so we have to be aware, alert and careful," he said.
