The 22-year-old driver was also taken to hospital but both have since been discharged.
The truck driver did not sustain any injuries, Mr Hamilton said.
"People do need to be aware of the road conditions. After a dry spell the road gets greasy after the rain. We also suspect speed may have been a factor in this," he said.
A stop-go sign was put in place with traffic slowly allowed through past the scene. A diversion had also been set up via Okawa Bay Rd through to Hamurana but was taken down about 9.30am.
