World Car Free day will be marked by free bus trips by the Nelson City and Tasman District Councils.
For Saturday September 21 and the following Sunday, all bus trips including the $4 late-bus service will be free for all passengers.
Saturday is this year's Zero Emissions day, and Sunday is World Car Free day. Nelson city council said in a statement that Zero Emissions day was a about "finding ways to take individual action to reduce emissions", and Car Free Day "speaks for itself".
"Changing how you choose to travel is an easy way to get started on reducing emissions ... this free bus weekend is an invitation for everyone to give the bus a try instead of taking the car. You'll also be helping to reduce congestion, plus catching the bus can be fun and sociable."
Mayor Rachel Reese said about 20 per cent of New Zealand's greenhouse gas emissions came from transport.
"We know we all need to make changes to address the climate emergency. We're asking everyone to think about what they can do differently, as we start to think about how we can do the same with how we operate at council," she said.
"Even just taking the bus one day a week instead of the car can make a big difference. This weekend gives everyone a chance to try the bus for free, and I encourage all Nelsonians to give NBus a go."
The council will also be using the free weekend of travel to help their review of public transport, planned for next year, as anyone who uses the buses on the free weekend is invited to give feedback on their journey via the council's Facebook or Instagram pages.
"You can say what you liked about it or give us your ideas on how to improve the service, and go in the draw to win grocery vouchers and free bus tickets," the council said.
There were also spot-prizes available for people posting photos of themselves or their friends and family using a free bus trip over the weekend.
