The government has given details on the vaccine pass set to be rolled out on Wednesday.
Covid-19 vaccine certificates, dubbed 'My Vaccine Pass' will sit inside people's digital wallet on their smart phones.
The certificates will be available to download later today for anyone who is double vaccinated.
The Covid-19 Response Minister Chris Hipkins told Morning Report he is confident the system will stand up to demand, but is urging people to wait a few days before downloading them.
He says each pass will have a QR code, although photo ID may be required for some places.
The government will also provide a phone number and drop in centres to help people who have trouble downloading the certificates.
