The single crewing of ambulances was of particular concern, Mr Thompson he said.
"The situations paramedics go into and the patients they attend are often unpredictable, especially where alcohol is involved." Tauranga Mayor Stuart Crosby said local government was unlikely to be the answer in the near future.
"I do not see a rate payer contribution to this service getting public acceptance as it would be deemed not to be a core service of council."
St John district operations manager Jeremy Gooders said assaults against paramedics in the region were rare with only one recorded in the Western Bay in the past three years.
Mr Gooders said verbal abuse was much more common than physical abuse but this was because staff were often arriving at volatile situations with emotions running high.
While Mr Gooders acknowledged single-crewed ambulances could leave a staff member or volunteer vulnerable, it hardly ever happened in the region.
He said ambulances in the Western Bay were crewed by two people 98 or 99 per cent of the time.
NZ First health spokeswoman Barbara Stewart echoed Mr Thompson's concerns at a lack of funding for the ambulance service.
Ms Stewart said paramedics were often asked to enter dangerous situations to do their job.
