Ms Barrie says staff are working with the council's city safe unit and tenant and stakeholder organisations to determine how criminal behaviour can be deterred — but the support of the community is vital.
"We report all these instances to police, and our message to the community is for them to support us with that. If any members of the public see suspicious or criminal activity in or near any of our buildings or sites, we want them to contact police and the council."
Councillor Dave Macpherson is involved with Waikato Volleyball which has a long-term presence at Te Rapa Sportsdrome, and says the thefts "reflect badly on us as event and sports organisers".
Cars broken into at Te Rapa Sportsdrome belonged to volleyball players and the organisation would be ensuring it had people monitoring the site when it had events on.
Hamilton's northern suburbs have been targeted in a wave of recent car thefts and break-ins, with Waikato Police asking residents to make sure cars are locked and valuables removed.
"We, like the people of north Hamilton no doubt are aware of a spike in vehicle crime in the city's northern suburbs," the Waikato Police posted on Facebook.
"We have our Intel section and a number of tactical workgroups working on resolving it.
There's are a few areas affected and the patterns are different. Residential areas have been hit at night, while cars in commercial/retail locations tend to be during the day."
The police ask that any car thefts be reported to them on the new non-emergency phone number 105.
