The Government's hoping to vaccinate 15,000 people against Covid-19 in a mass three-day session.

The event at Manukau's Vodafone Event Centre late this month is for MIT staff, students and their whānau.

Response Minister Chris Hipkins told Andrew Dickens it's a good time to test setting up mass vaccinations.

"One of the things that we have to test out through this is our ability to stand up these kind of events with a relatively short lead-time. 

"A lot of preparation has gone into getting the site, getting the staff, and so on."

Hipkins says everything has to be right before similar events can happen again.

Meanwhile, an Auckland mother's been told she can't keep paying $10,000 a year for a teacher aide for her eight-year-old son.

It came a day after she emailed Education Minister Chris Hipkins, arguing there's not enough support for all learners at existing state schools, and suggesting the ministry pay for the help.

Hipkins says that while parents are able to pay for additional support for their child, it has to be done as a donation - and it is actually against the law for schools to invoice parents.

"They have to be voluntary. Schools can't say to parents they have to pay these extra fees."
