It is hoped a new St John rapid response unit will be able to halve response times for the most serious incidents in Dunedin.
The new vehicle arrived in the city yesterday, and will be in use from Monday morning.
It was the first new St John resource in the city for 20 years, St John coastal Otago territory manager Doug Third said.
The new resource also meant a staffing boost.
Four intensive care paramedics in total, recruited from existing staff, would crew the unit in shifts, with another staff member available as a relief crew member, he said.
