Four youths were seen on CCTV footage vandalising the all-weather athletics track in Masterton, leading up to one of the track's biggest events of the year this weekend.
The tag Killer Beez Masterton was found in several locations around the facility last week and police said while the tag itself is gang-related, "there have been no reports of gang-related behaviours recently linked to the group".
"From my understanding, this incident was just a group of youths using that tag and it's something we'll just have to keep an eye on," Police Senior Sergeant Mike Sutton said.
Masterton District councillor and athletics coach Mark Harris said it was a "shame" the youths had taken it upon themselves to "do the artwork" just before the Wellington Centre Track and Field Championships which is held at the track this Saturday.
"The tagging was reported to me by someone else on Wednesday night at about 6pm last week," he said.
