Secondary students at the summit said they wanted the system to give Māori greater recognition.

Ardern said there was no evidence of broad flouting of self-isolation but wanted the system improved.

Dr Read said she also wanted the system to be improved and welcomed the comments in Mr Upton's report.

He wanted the system accessible to the average person, so all the gadgets he used are made of off-the-shelf equipment.

She wanted the system changed so families and midwives can be allowed more say in the courts over what happens to babies.
