Covid-19 Response Minister Chris Hipkins does not know how many young people have received surprise invitations to book in for a vaccine.
Those over 65 or with underlying serious health issues are currently being vaccinated.
However, some people in their 20s are being contacted by text to book their vaccine and say they have no idea why.
Hipkins said he had heard of reports of this, but has not been advised it is a systemic problem.
