Two staff were let go from Port Otago when the company’s vaccine mandate began late last year.
Port Otago chief executive Kevin Winders said 100% of the 300 staff at the Otago Regional Council-owned company were vaccinated and as of Monday this week 91% had received their booster shots.
Surveillance saliva testing was typically undertaken twice a week and at this stage there had been no Covid-19 cases at the port, Mr Winders said.
"With Omicron at our doorstep we are in good shape," he said.
"It still will impact us, but we think to a lesser extent.
"We’ll be able to look after our region’s cargo, both in-bound and out-bound to keep the supply chains going."
Port Otago chairman Paul Rea said the company’s highest priority at present was to minimise the impact of Omicron on Otago’s exporters.
Because the port was a "border-facing business" the company had had priority access to the vaccine early last year, so its staff were some of the first to be vaccinated in the country.
But staff had also largely welcomed the opportunity to be protected from Covid-19 early on.
"We also had the immediacy of ‘every ship that comes in from offshore was a threat’ and our staff protected themselves or thought through the protection they needed to protect themselves against that," Mr Rea said.
"The rest of New Zealand that weren’t so much border-facing probably took a little longer to realise and act on that."
