It has two smaller pumps for fighting rural fires, which it can get close to because of its 4WD ability, adding to the brigade's engine and pump capabilities.
Chief fire officer Don Gerrand said firefighters were "rapt" with the engine, which was unveiled last Sunday.
He said it had already been used to attend two fatal accidents.
Mr Gerrand said the brigade attended 300 calls a year, which included fires, accidents and medical emergencies.
"Because things have changed we're now fire and rescue and we're doing that sort of work.
"When St John [Ambulance] is busy with another call we'll go instead."
He said the brigade's rescue van had become too small for the equipment the crew needed while the new appliance could also carry five firefighters.
Grants from Pub Charity and Fonterra as well as two years of fundraising helped secure the engine, which was ordered a year ago.
