"Both pedestrians and drivers should pause and try and catch each other's eye so there's no confusion around who's going first.
"We want pedestrians to look out to keep themselves safe, look out to keep their children safe, and look out to keep their parents safe, so everyone gets where they want to go safely."
The posters and painted pavements will start being rolled out from Wednesday, November 20.
The New Zealand Official Road Code describes courtesy crossings as: "made of bricks or paving and often raised above the level of the road.
"Although not official pedestrian crossings, they do provide a place for pedestrians to cross. Drivers should be courteous to pedestrians using a courtesy crossing".
A Hastings District Council spokeswoman said because the paving stones on the crossings are the same as those used on the footpath it can cause confusion, but the footpath does not extend across the road.
To help make it clear and to encourage pedestrians to be ready to give way, and drivers to continue to be courteous, Hastings District Council will start installing signage and road markings from this week.
Permanent painted paving signs stating "LOOK" have been designed to catch the eye of someone looking down or straight ahead, as a cue to look up and look around for oncoming vehicles.
Posters are being installed on existing council-owned poles at the crossings.
Once awareness has grown, in about two to three months, the posters will be removed and only the pavement signs will remain.
