Over the last three weeks, Waikato Hospital has been asking gang members to remove their patches before visiting friends and family.
Hospital staff say the trial has been a success, so will become policy as of today.
Twenty-five gang members have been asked to remove their patches before entering in the last few weeks, and all have complied, says security manager Dean Ria.
"This has been at a time when we’ve had both Black Power and Mongrel Mob members at Waikato Hospital visiting fellow gang members," he says.
"Nursing staff have been very appreciative of the rule which allows them to do their jobs without intimidation."
The policy extends to all Waikato DHB hospitals.
Whanganui banned gang patches city-wide in 2009, and other towns are considering similar bylaws.
