Hawke's Bay Area Commander Lincoln Sycamore said the region was currently experiencing a "small spike" in similar incidents and police were "actively investigating" these incidents.
"We experienced a similar issue earlier in the year and initiated an operation to target car thieves," Sycamore said.
"We identified a number of offenders who were referred to Youth Services.
"We have also been aware of some information being spread over social media among younger people encouraging the taking of motor vehicles."
He said it was important to note it was not only Demios targeted.
"Any older vehicle typically those that don't have immobilisers and/or alarms are susceptible," he said.
"We ask anyone witnessing suspicious behaviour around vehicles or anyone who has information about who is committing these crimes to contact us."
From January to May this year a group 30 teenagers - some as young as 13 - were believed to be responsible for stealing more than 100 Mazdas, many of them Demios, in Taranaki.
RNZ reported that police were aware of videos being posted on Snapchat and also had reports of them appearing on the TikTok platform.
Police advise the following preventative measures be taken to avoid car theft
- Installing alarms or steering wheel locks to vehicles if they don't have them. These are a visual deterrent and immobilise the vehicle
- Use of sensor lighting and CCTV to monitor areas where vehicles are typically parked if not in a secure garage
- Consider parking susceptible models in behind newer vehicles on the driveway preventing them being removed
- Never leave valuables in your car especially wallets, cash, bank cards et
