A nurse who's convinced reluctant port workers to get the Covid-19 vaccine says it's all a matter of explaining clearly how the injections will protect colleagues, friends and family from the virus. Nearly half of port workers have not yet had their first dose of Pfizer and the Maritime Union wants more nurses like Bronwyn Robinson visiting sites to help allay fears and misinformation. On Thursday Union national secretary Craig Harrison told Morning Report he'd watched as Robinson got hesitant staff at Napier Port to change their minds. She told reporter Jean Bell what they'd been worried about.
