Many port workers aren't vaccinated for Covid-19, because they aren't yet eligible.
Covid-19 Response Minister Chris Hipkins says he's concerned that 44% of port workers have yet to receive a single dose.
He says it's a worrying sign of vaccine hesitancy, caused by the spread of misinformation.
But the chairman of the Port Company CEO Group, Charles Finny, says most of those workers would be getting a jab, if they could.
He says only a small proportion of workers are eligible -- because they're deemed high risk, or deal directly with ships.
