Growing demand for ambulances in Northland is putting increasing pressure on the service.
The number of incidents attended by St John in Northland increased each year in the past six years to 15,605 callouts in 2014.
In Whangarei, the number of St John attendances increased from 8177 in 2009 to 10,074 last year. In the Mid North, there were 2862 attendances in 2009, compared to 3470 last year, and in the Far North, there were 1820 attendances in 2009, compared to 2061 last year.
St John acting district operations manager for Northland Ben Lockie said demand on resources was ever increasing.
"Northland has an increasingly ageing population and a growing population," he said. "In the seasonal and holiday period, there's always a significant increase in our workload. We've taken on extra staff to meet demand and during peak times, we put on extra crews."
