Some of the problems with the Vaccine Pass site which continued late into yesterday, appeared to be the result of underlying glitches rather than the volume of visitors leaving some tech industry experts surprised.
Meanwhile, several questions lingered for users and businesses about how the new system will work in terms of scanning, enforcement, and fraud protection.
Many Kiwis have reported they were unable to access the site or were getting ‘Something Went Wrong’ messages that indicated something going haywire with the verification system.
Of course, there is no immediate rush, Vaccine Passes won't come into effect until the traffic light system is introduced.
Many businesses were unsure how the system will work from their end - either in terms of how they would scan QR codes, how they could prevent fraud or at which point they were required to scan people.
