A blockade has been put in place to the entrance of a Mount Maunganui business this morning.
A caller to the 0800 SUNLIVE news hotline says there are about seven people blocking access to Ballance Agri Nutrients.
"They have built some sort of platform thing in the middle of the road.
"Police are at the scene. It will probably cause some delays."
Photos sent to SunLive show protesters holding up signs about calling for clean air.
They are also protesting the use of phosphate in New Zealand.
A police spokesperson says there have been reports of traffic delays in the area.
