St John Ambulance in Christchurch says a $2.8 million grant has enabled it to replace emergency equipment damaged in last year's earthquakes.
The grant, from the Christchurch Earthquake Appeal, has been used to fund St John's mass casualty incident equipment, emergency vehicles and medical and emergency equipment.
The Prime Minister, John Key, toured St John's South Island headquarters in Orchard Road on Friday afternoon.
Chief executive James Wood says the grant will allow it to prepare for any future event anywhere in the South Island.
He says the grant has restored the charity to full service in the region.
