Sergeant Richard Van Asch said the footage showed a number of people leaving the scene of one of the 10 vegetation fires lit over the past two months.
“We are following strong lines of inquiry as to some of the people involved,” he told the Selwyn Times.
He would not say how many people or what age they were.
Three more vegetation fires were lit last week, Rolleston volunteer fire brigade deputy chief Graham Peterson said.
They were at Stonebrook playground, near the Rolleston Scout Den and beside Three Trees Learning Centre, next to Foster Park, he said.
Two fires were reasonably small but the third by Three Trees Learning Centre was lit in long grass.
"It was dealt with reasonably quickly but it could have had a lot more consequences.
"It backs onto houses and things like that once again. It doesn’t take long, especially with things drying out to change things."
Peterson urged anyone who saw something suspicious to phone the police or 111.
"The quicker we find out about it, the better,” Peterson said.
Van Asch said it was possible there is more CCTV footage in the community that shows the arsonists.
If that was the case police needed to see that footage, he said.
Members of the public could phone 105 or access the service online to provide the information.
Kenyon said there was concern the small fires being lit could lead to bigger blazes.
“We’re concerned that they’re going to get bigger or properties going to be damaged.”
