Event organisers are working through logistics of how vaccine passports will work at summer events.
The Government's started consulting with concert, festival and other event organisers, about introducing making proof of vaccination mandatory.
The vaccine passports could be printed out, or shown on a person's phone.
Rhythm and Alps Founder and Director Alex Turnbull told Mike Hosking it needs to be implemented through ticketing.
"So the logistics are based around making it as easy as possible and painless. No one wants to walk around with a mask and a phone for the rest of their life."
