The companies are part of InMotion Group, which also operates Fullers, 360 Discovery, Roam Experiences and Waiheke Bus Company.
ManaBus was first launched as a budget travel option in 2014 by Scottish transport entrepreneur Brian Souter, adding to a portfolio that included Auckland urban bus companies Howick and Eastern Buses, the Wellington-based bus service Mana Coach Services and Waiheke Bus Company, as well as the Auckland Fullers Group ferries and the 360 Discovery cruises.
In May 2015, Souter's company acquired rival Naked Bus in a bid to expand the company's footprint across the South Island.
At the time of the acquisition of NakedBus, Manabus said the combined entities across the entire portfolio transported more than 13 million customers a year and employed 670 people.
