"We want to look at a programme which achieves our aspiration of a wider uptake [of te reo Maori] by the student body. We've preached the compulsory thing for years and really haven't thought too hard about how we're going to implement it ... I think this is a practical solution," he said.
The Education Ministry said New Zealand had no compulsory subjects in the curriculum. But it had eight learning areas - English, the arts, health and physical education, mathematics and statistics, science, social sciences, technology - of which seven had to be offered to all students in years 1 to 10.
Mana leader Hone Harawira said his party wanted te reo to be a core subject.
But Labour's Kelvin Davis, a former principal who is also standing in Tai Tokerau, supported the Maori Party idea. "I actually think it's a good idea to be honest. I would love every child in New Zealand to want to speak Maori ... but I think if there were compulsion there'd be a massive backlash by unenlightened New Zealanders."
