Part of State Highway 29 is blocked after a truck lost its load near Barkes Corner at Pyes Pa.
The truck is blocking the highway between the roundabout and the intersection of SH29 and Takitimu Drive.
A reporter at the scene said Tauranga-bound traffic was being diverted through Takitimu Drive as emergency services cordoned off the east-bound lane on SH29, heading towards Pyes Pa.
West-bound motorists were still able to use the highway but traffic was heavily backed up and travelling very slowly, the reporter said.
The incident is the latest in a string of highway closures following crashes around the region today.
