Holding a tertiary student ID has many perks - discounted movie tickets and cheap gym memberships - but they are useless for Wairarapa students commuting by train to the capital.
University and polytechnic students using the Wairarapa Tranz Metro line are required to pay full adult price while secondary students pay the child price, a discount of 50 per cent.
The cheapest option for students travelling to Wellington from Masterton is to buy a monthly pass for $432. The same pass for children, including secondary school students with school ID, is $216.
One Victoria University student who commutes three times a week from Carterton thinks this is "the stupidest thing in the world".
"God knows why you give high school students - who live with parents who still pay for just about everything they do - cheaper rides and not tertiary students who are making pretty much no money," Simon Switzer, 20, said.
