"Within the space of half an hour we have four crashes and then at 12.16am, midnight, on Takitimu Drive a vehicle lost control and hit a tree. Than at 7.03am this morning there was a three car collision on SH 2 near Wright Rd, Aongatete," Mr Campion said.
There were no significant injuries in any of the collisions "but all of these crashes were preventable".
Mr Campion said of five of the crashes were the result of driver's inattention.
''It's about concentrating on what you are doing. Three were rear-end crashes, two were intersection crashes," he said.
"I know I sound like a broken record but people need to take extreme care out there, particularly under adverse weather conditions. They need to watch their speed, following distances, etc. They need to pay attention to what they are doing."
Heavy rain fell throughout Tauranga after 5pm yesterday, contributing to a total rainfall of 6.2mms of rain falling before 10pm.
