A rare moment of agreement across the political divide as National's Leader says he's supportive of the idea to scrap the school decile system.

Christopher Luxon told Kate Hawkesby deciles were too broad.

He says what they proposed was to use data which highlights the families who are doing it tough, and schools are allocated money in an anonymised way, based on the families at their school.

The Government will implement a new Equity Index to replace the decile system.
