"The reality is that in an awful lot of schools driver education is happening already. Financial literacy is happening in an awful lot of schools already, and civics programmes are happening in an awful lot of schools already," he said.
"It's a real kneejerk reaction. They must have listened to some talkback radio and thought, 'We must fix that.' It's that low-level thinking that is not helpful."
Act leader David Seymour also attacked Ardern's proposal, saying civics classes "risk turning into political indoctrination sessions".
"Political parties on both sides need to do better at reaching young people. Handing this job to teachers is a cop-out. It's not the state's job to tell kids to vote Labour," he said.
"There's a serious risk of unions influencing civics class content. Notice how it's conspicuously the left pushing for these classes? Labour is suspicious of religious education in schools, but seems fine with using the school system to push a political agenda."
However Road Transport Forum chief executive Ken Shirley, a former MP for both Labour and Act, welcomed the driver education proposal.
"The lack of driver licences amongst young people is a really big issue for our industry. There simply are not enough young people coming through to drive the trucks needed to help grow the economy," he said.
"It is a very serious issue right across the economy, not just in road transport. A recent NZ Institute of Economic Research report showed only 10 per cent of 18- to 24-year olds on jobseeker support had a full licence and nearly half had no licence at all."
