The page told the Selwyn Times: "Us poles are under-represented and we need to stand up for ourselves".
Senior Sergeant Stills said police are in consultation with the New Zealand Transport Agency and the district council over proposed prevention and safety changes to the intersection.
He said it includes the possibility of having a right turning arrow for vehicles heading north on State Highway 1, turning into Rolleston Drive.
"And also potentially just some warning signage for left turning traffic being aware of vehicles coming from their right," Senior Sergeant Stills said.
However, he said a date has not been set for when the proposed changes could take place.
A NZTA spokeswoman said 13 traffic poles, including five in the past three months, have had to be replaced due to "accident damage."
The spokeswoman said the cost to replace the poles depends on the extent of damage and location of the pole.
"Traffic poles can cost thousands of dollars to replace . . . anything between $5000 and $10,000," she said.
However, the spokeswoman said "where possible" repair costs are recovered from the person responsible for the damage or their insurer.
She said it generally installs socket foundations on poles which have a history of accident damage to reduce the cost of future replacement.
