In the transport category, the biggest reduction was a 7 per cent decrease in National Travel Assistance kilometre claims by patients who needed to travel, mostly to Auckland Hospital.
This saved 226,000km worth of travel by patients, due to more treatment and services being available in Northland.
A 3 per cent decrease in use of the board's staff fleet fuels saved almost 20,000 litres. Six electric vehicles, including the patient shuttle at Whangarei Hospital, have been added to the fleet.
One area where the health board did not make the cut was an increase of 7 per cent, or 53 tonnes, going into landfill. Construction waste from the Bay of Islands Hospital redevelopment works was largely responsible for this number.
Recycling programmes for medical products like IV bags, oxygen masks, tubing and anaesthetic bottles are expected to make a difference in next year's audit.
