Police are investigating an alleged violent incident between three males at the Tauranga Netball Centre on Saturday.
It was alleged a hammer was involved in the incident, although there were no injuries reported.
In an email to members, Tauranga Netball Centre apologised to those who witnessed the incident.
"Apologies to any members who were present during the violent incident between three males on Saturday at netball," the email said.
"This behaviour is absolutely inappropriate, to say the least, and is not acceptable anywhere, let alone in front of tamariki at sport grounds."
