There's some good news for the nation's largest ambulance service.

Associate Health Minister Casey Costello has announced Hato Hone St John will receive $21 million in additional Government funding.

She says St John has also settled its pay dispute with unions, with no further industrial action planned.

Costello explained that New Zealand First has a coalition agreement to meet a greater portion of the ambulance service's annual budget - but this will go a long way.
