Since Friday, December 3, getting access to businesses, public facilities and services can require a Proof of Covid Double Vaccination Certificate.
For many people, particularly the elderly, this has caused panic.
"For most people, using the online portal is the fastest and easiest way to get a My Vaccine Pass," says Ministry of Health group manager national digital services Michael Dreyer.
"People without a smartphone or access to a computer can get their My Vaccine Pass by calling 0800 222 478 to request a My Vaccine Pass. Someone can call for a person on their behalf, but they must have their permission.
"For those that do call the 0800 number, we ask people to continue to be patient and kind to our staff as they assist with queries and help people generate their My Vaccine Pass. If you can't get through immediately please call back later.
