From next month, Napier residents will be unable to recycle some types of plastics.
Grades 3-7 are no longer recyclable, because there is no international market for them.
Director of infrastructure services Jon Kingsford said for the past year contractors have had to stockpile plastics, because shipments are unpredictable.
There is also no guarantee that the less valuable plastics will be recycled when they have been exported.
"We don't want the landfill to fill up unnecessarily with plastics, but neither do we want our contractor to be put in the position of having to store these unwanted items.
