Mrs Graeme had kept sheep at the property for 45 years.
"Beside our pets they were our lawnmowers," she said.
Tauranga City Council animal services team leader Brent Lincoln said he visited the property yesterday, and as of last night had no leads on the attacking dogs.
"It's the worst we've had in Tauranga in many years."
However he said there would likely be no linkage to dogs that attack sheep in this manner, and those that harm humans.
"The sheep run and it excites them."
He said anyone who had any information should contact the Tauranga City Council on 07 577 7000.
