Thank you for your request of 31 July 2025 to the Department of Corrections – Ara Poutama
Aotearoa, requesting information about National Emergency Alerts and the discovery of
contraband cell phones in prisons. Your request has been considered under the Official
Information Act 1982 (OIA).
The safety and security of our sites, our staff, and the people we manage is our top priority.
We take contraband cell phones extremely seriously, as they bypass the managed and
monitored communication systems available to prisoners. These systems are critical for
identifying and preventing prisoners from contacting victims, intimidating witnesses,
tampering with evidence, introducing contraband, and orchestrating violence and other
offending. Some prisoners go to extreme lengths to continue causing harm from inside
prison, and contraband cell phones can be used by prisoners to continue coordinating
criminal activities while they are in prison.
Corrections places significant emphasis on preventing and detecting contraband in prisons
and we are constantly working to stay one step ahead of new methods used to introduce it.
We use a wide range of methods to prevent contraband from entering prisons, including:
• Using scanners and x-ray machines at entry points.
• Extensive prison perimeter security.
• Camera surveillance in prison visit rooms, along perimeter fences and at entry points
• Requiring prisoners to wear closed overalls when in visiting areas to prevent
contraband being hidden on them.
• Checking prisoner mail and property for contraband.
• Monitoring prisoner communications, including phone calls.
• Operating specialist detector dog teams that detect drugs, and other items not
permitted within prisons including cell phones.
• Banning visitors who attempt to bring contraband into prisons.
The emergency mobile alert system would not be an effective tool for detecting contraband
cell phones, as these devices are typically turned off unless in use, in flight mode or with sim
cards removed.

You requested:
Can you please provide information held (happy for this to be at an aggregate level)
on the number of contraband cell phones discovered, by day over the year to 31 July
2025. I will then use this to compare to the dates which emergency alerts were
pushed by the National Emergency Management Agency.
Please see attached as Appendix One, the number of incidents in which contraband cell
phones were discovered within the requested timeframe, broken down by date. For your
awareness, the contraband cell phones located on 30 and 31 July 2025, were not as a result
of the National Emergency Alerts.
Please note that this response may be published on Corrections’ website. Typically,
responses are published quarterly or as otherwise determined. Your personal information
including name and contact details will be removed for publication.
I hope this information is helpful. I encourage you to raise any concerns about this response
with Corrections. Alternatively, you are advised of your right to raise any concerns with the
Office of the Ombudsman. Contact details are: Office of the Ombudsman, PO Box 10152,
Wellington 6143.
