One Pererika St business owner, who did not want to be identified, told The Daily Post he wanted signs put up warning people to slow down.
He said the skate park was a popular place for children, especially during the weekends and school holidays. He said he would regularly see about 50 children using the skate park.
The man said he saw Saturday's incident and said the boy had looked both ways before he crossed the road.
"He did look and then darted out and hit the bus," he said.
"The kids that use the skate part are usually pretty good. A lot of us who work around here do remind them they need to look both ways before they cross the road."
He said motorists were meant to stop at the intersection of Pererika St and Ranolf St, but they very rarely did.
"People need to actually stop and they should put some signs up telling people to slow down for children."
Police said they were investigating the incident but no further information has been released.
Meanwhile, Rotorua 6-year-old Hineraukura Fraser-King is still in a rehabilitation facility in Auckland.
Hineraukura was hit by a car on Sala St on May 5.
She was initially in Auckland's Starship Hospital but moved last month to Wilson Home, which is a rehab facility.
Hineraukura's family said she was making great progress. She can now eat without a feeding tube and her broken bones are healing.
It is still unclear how long she will remain in the rehab facility.
