Medsafe has approved changes that extend the useful refrigerated shelf life of an unopened vial of the vaccine from 5 days to 31.
It follows new data from Pfizer about vaccine storage.
Once at fridge temperature, the vial can't be returned to the freezer and must be disposed of after 31 days or on the vial's expiration date.
The change takes effect immediately, and vaccines distributed from next Wednesday will have updated labelling.
Covid-19 Response minister Chris Hipkins said today it was helpful for the vaccine programme, meant it would be easier to transport and would make it more accessible.
Great news for the #COVID-19 vaccine programme! The Pfizer vaccine can now be stored at normal fridge temp (2C to 8C up to 31 days). This means it’s easier to transport and will be more accessible at places like local pharmacies/GPs’ surgeries. https://t.co/PegxBPPuoc

The vaccine still needs to be kept at ultra-low temperatures in the longer term, for up to six months.
