Traffic throughout Tauranga is at a gridlock this afternoon.

A number of motorists have reported heavy traffic on either side of the city, with wait times of up to an hour or more in certain areas.

One motorist travelling on State Highway 2 says traffic is at walking pace through Te Puna.

Her comments are backed by a caller to the 0800 SUNLIVE hotline who says SH2 traffic coming into the city can be seen backed up for miles past Katikati.

'My son and his wife are travelling out of Tauranga towards Whitianga but say the stream coming in is horrendous.”

Another caller who has driven past the Baypark area says traffic is heavy in the area.

A number of speed restrictions, diversions and road closures are in place as the Bay Dreams festival takes place.

NZTA has advised motorists to take caution on roads throughout the area.
