Strange said the change would also make it easier and more affordable for people to get to things like health appointments.
"Many of our older people are on a fixed income, and they've told me they're really excited to have the freedom of unrestricted travel at no cost," she said.
For Hamiltonians, it will mean free travel to Auckland on all Te Huia services and by bus to regional communities like Raglan, Te Awamutu, Cambridge and Matamata.
For those people living in rural towns with a bus service, it will connect them to Hamilton for hospital appointments, as well as to the gardens, zoo and shopping centres.
