System description

Each day, Justice sends Customs, by encrypted online transfer, details of serious fines defaulters for the purpose of creating 'interception alerts' or 'silent alerts'[1] in the Customs system (CusMod). The most serious cases attract an 'interception alert', which results in the traveller being intercepted at the airport and required to pay (or make an arrangement to pay) their fine or reparation or face arrest. The other cases involve a 'silent alert' which uses information about the traveller for enforcement action after their entry or (re-entry) to the country.

Fines defaulters who have interception alerts recorded in CusMod are those where: 

  • Either
    • any amount of reparation is owing and
    • a warrant to arrest has been issued and
    • the warrant covers at least part of the reparation outstanding;
  • Or
    • court imposed fines greater or equal to $5,000 are outstanding and
    • a warrant to arrest has been issued and
    • the warrant covers at least part of these court imposed fines. 

Silent alerts are created for fines defaulters not subject to an interception alert but meeting the following criteria:

  • fines equal to or greater than $1,000 are outstanding and
  • a warrant to arrest has been issued and
  • the warrant covers at least part of these outstanding fines.

For each fines defaulter, Justice supply Customs with the following information: 

Person profile number Family name Given names
Date of birth Gender Alert type

As an individual passes through the border, a Customs official scans their passport into the CusMod system. The CusMod matching programme converts details from the passport into an alpha-numeric code for matching against alerts. Alerts are generated for 'A' matches, which require a 91-100% match outcome based on a weighting system. For instance, date of birth and family name each has a percentage attributed to it which add up to 75% towards the overall weighting score.

Matches triggering an interception alert are directed to a Customs official who notifies NZ Police. A police officer conducts an interview with the individual to confirm their identity and that the individual is the same person as the alert, whether outstanding fines exist, and if a warrant to arrest remains in force.

Fines and warrant to arrest information is obtained by phoning the Justice Contact Centre. If the Police are satisfied that the individual is not the person on the alert, they are left to continue on their journey and a report is filed.

If the facts are verified, the individual, through a phone call with a Justice official, is given an opportunity to pay the outstanding amount or to enter into an arrangement to pay. If no payment is made, or arrangement entered into, the Police have discretion to execute the arrest warrant, in which case the individual will be stopped from travelling and brought before a court.

After an interception, the alert is usually removed from CusMod in the next daily update.

Silent alert information is not displayed to Customs staff but is notified electronically to Justice for potential use in the related INZ/Justice Fines Defaulters Tracing Programme. Silent alerts do not result in individuals having their travel interrupted.

[2] The number of alerts on arrival or departure will not necessarily equal the total number of people intercepted as a person can trigger multiple alerts in a given period.
