A group of Havelock North residents spent Saturday morning protesting with painted placards outside a retirement village.
The "peaceful demonstration" was against the increasing number of cars using the Mary Doyle Lifecare Complex's back entrance on Goddard Lane.
"We decided now is the time to let people know we've had enough," said organiser and resident Grace Terry.
When Mrs Terry and her husband Roger moved to Goddard Lane five years ago, they were told the number of traffic movements in and out of the entry would be 30 per day.
More recent traffic counts found this number to be 143 per day.
