Simon Wilson is referring to the news that Labour has opposed the idea of metro schools, being schools in built up areas that might use community playing grounds rather than have their own.
It shows how reflectively knee-jerk Labour is to any change from their 1970s views of schooling. They are against metro schools, against online teaching schools, they are against charter schools. If National proposed kura kaupapa schools they would probably be against those also.
As it happens we already have a couple of metro schools, and as Wilson points out it is nuts to oppose them with such huge population growth forecast in our CBDs. Sure not everyone will want to go to a metro schools, but it is about choice and having schools built near where people live.
Labour really are dismal when it comes to education. They have no vision for it beyond opposing change.
