The search for the boatie missing off Tauranga's coast continues today.
The missing boatie was believed to be 39-year-old Karl Earwaker of Te Awamutu.
Police, Coastguard, Navy, and search and rescue volunteers have been searching for Mr Earwaker since Tuesday when his boat was found capsized two nautical miles south of Mayor Island.
The search today was being supported by the Navy using sonar equipment to search the sea floor.
There would also be a shoreline search of the southern end of Mayor Island by LandSAR volunteers and a Coastguard vessel.
