All unvaccinated staff at Lyttelton Port will be stood down on full pay this morning as a temporary measure.
Port staff who have been received a vaccination, are required to show their vaccination card when turning up for work.
A spokesperson for the port company said more than 95 per cent of 1A or border-facing staff are vaccinated - equating to about 300 workers. The other 5 per cent have been redeployed.
Of the other approximate 300 staff who are not required to board vessels including those working in an office, 85 per cent are vaccinated.
