Mrs Edmunds has raised the issue with council staff and elected members several times in the past three years but continued to keep the big berm tidy. More recently she appealed to Whangarei Mayor Sheryl Mai, who wrote in December confirming the no-exceptions policy.
Mr Sowry has done the mowing in the past and Mrs Edmunds paid for the petrol but he has a health problem that means he can't mow any more.
Mrs Edmunds pays for her own lawns to be cut and cannot afford the quoted $80 a fortnight for the berm, which fills two wool sacks of clippings, too much for their composts.
"It's not really a berm. It's beyond reason to expect us to mow that amount," Mr Sowry said. "There should be an understanding over a certain size."
Every few weeks council contractors use two large mowers to cut a reserve across the road, leaving the neighbours wondering why they can't whip across and do the berm.
