Expect to see more yellow around Northland during emergencies, sporting and community events as St John Northland has three new ambulances.
The new yellow ambulances have replaced old white ones and are based on the internationally recognised colour of the ambulances many European countries have.
District Operations Manager for St John Northland Tony Devanney said the bright yellow colour of the ambulances will make them more identifiable.
"They'll be more visible. The white ones can blend in during the day so you'll be able to see these ones better."
Four more of the yellow ambulances are expected over the next 12 months.
