Recruitment was now underway in Tokoroa, Ohakune, Timaru, Westport and Whangarei which were all set to be double-crewed by the end of the year.
"The double crewing of all emergency road ambulances will help ensure patients get the best available care when they need it. It also enhances the safety and well-being of our dedicated ambulance staff," Coleman said.
"The new roles include a mix of ambulance staff to ensure double crewing can occur. This will be particularly beneficial for regional and rural communities."
Recruitment was also underway for more paramedics who could be sent on rescue helicopters.
"St John is in the process of recruiting two intensive care paramedics for the Whangarei helicopter service. More crew will be recruited for helicopter services in Hamilton, Palmerston North, Napier and Christchurch," Coleman said.
Research released last month showed the long-term chance of survival of cardiac arrest patients was 5 per cent higher when they were treated by two St John staff rather than one.
