The Rotorua Lakes Council has received legal advice backing its position that yellow and black signs put up around the city are illegal.
But the group responsible for them - Rotorua District Residents and Ratepayers group - says it would consider seeking its own legal advice over the matter.
The council's compliance solutions manager, Neven Hill, said as at January 18, 10 signs were found to be outside the rules of the District Plan and another site check would be carried out next week.
He said any sign not on a road came under rules set out in the District Plan and the council deemed the yellow and black signs to be temporary.
Temporary signs are allowed to be up for no more than three separate six-week periods, must be less than 3sq m in size and no greater than 2m in height. Permanent signage requires a resource consent.
