"Not only will this service take the stress out of commuting but the carriages will be comfortable and equipped with wi-fi, allowing passengers to use their travel time productively."
Twyford said the service will initially start with a four-carriage train which can carry 150 passengers - with two morning peak trains and two return afternoon peak trains.
"As demand grows, it can be expanded to a five-carriage train carrying up to 200 passengers," Twyford said.
The service is expected to roll out of Frankton in Hamilton in mid-2020, will stop at The Base in Rotokauri before going onto Huntly and finally stopping in Papakura in Auckland, where passengers can change on to the Auckland Public Transport Network.
Future stops may include Te Kauwhata, Pokeno and Tuakau.
