Farmers worst affected by the July flooding will get free diesel from the Eastern Bay Energy Trust.

In a special rural relief package announced yesterday, the trust said it was working with Shell and its subsidiary Mini Tankers to supply more than 61,000 litres of diesel.

Farms will receive either 600, 400 or 300 litres of fuel according to the amount of damage sustained.

Bought from Shell at a specially subsidised rate, the diesel will be delivered over the next six months.

Trust chairwoman Toni Owen said much of the clearing-up was in remote rural areas and not obvious to the general public.

"Bulldozers and other heavy machinery use massive amounts of fuel, and this is one way the trust can assist with the early economic recovery of the region," she said.
