The Greens want to build up to $200 million in cycle lanes and walkways around schools if they are in government, and funding would be redirected from "low-value" projects such as the Holiday Highway north of Auckland.
The number of children walking and cycling to primary and intermediate schools has dropped from more than 50 per cent in 1989 to 30 per cent.
The Green Party revealed in a policy paper published this morning that it hoped to reverse this trend by investing $50 million a year over four years into infrastructure such as cycleways. If it was successful, the policy would reduce congestion, carbon emissions and child obesity rates.
Transport spokeswoman Julie-Anne Genter said that the party's total spend of $100 million on cycling and walking projects per year would be a "drop in the bucket" of the transport budget — about 3 per cent.
