Labour's pushing back on the suggestion its numbers don't add up for a proposed cap on bus and train fares.
The party's promising to cap fares at $20 a week in Auckland, Wellington, and Christchurch, and $10 elsewhere.
It's estimated to cost $65 million a year – the funding coming from the Land Transport Fund.
Transport spokesperson Tangi Utikere told Heather du Plessis-Allan the amount's calculated by looking at current public transport numbers.
He says there are people who only take monthly or weekly trips, and the overall goal is to help households doing it tough.
Utikere says regular commuters could save about $1,200 a year.
