Auckland won't be scrapping its green food scrap bins any time soon.

Whanganui District Council is dropping its kerbside service to save a 1.5 percent rate increase.

Local Government Minister Simeon Brown believes Auckland could do the same.

It costs much more to offset carbon with food waste bins - than the carbon credits system.

Auckland Council Waste Solutions general manager Justine Haves says the service reduces landfill waste.

"We regularly hear from communities that they don't want more landfills, so in order to achieve that, we need to achieve waste minimisation."
