A woman was contacted by the Ministry of Health's tracing team four and a half weeks after she came into contact with a confirmed Covid-19 case.
She took a regional flight on 17 March and ten days later developed symptoms of the respiratory virus.
The woman was denied testing, until she could prove contact with a confirmed case, or had heard from the contact tracing team.
Instead a week later she found a media report naming the regional flight she had taken as one with a Covid-19 case - only then was she able to be tested.
The woman, who RNZ has agreed not to name, spoke to reporter Charlotte Cook.
