The Ministry of Justice says it is going to move about 100 collections registry officer positions to working from home over the next 13 months.

Collections officers handle and process fines and reparation inquiries, and enforce payment when required.

The ministry says the collections officers will be working from secure computer systems in a paperless environment and will not be able to download or print information. Their computer can only be used for ministry work and any data is fully encrypted.

It says collections officers can choose when they work their contracted hours between 7am to 9pm Monday to Friday and 9am to 5:30pm Saturday, up to a maximum of 10 hours per day. A break of two consecutive days is required each week.

"The vast majority of people now pay their fines online or over the phone, and these staff do not need to be in any specific location to do their job," says General Manager Collections Bryre Patchell.

"We began looking into having people work from home some time ago, and in 2013 began a pilot to test the practical realities of this. It turns out the people involved are happier and more efficient when they work from home."

The ministry says the changes do not affect services to the public, who wills till be able to pay fines over the phone, online or in person at a Westpac branch, or at a District Court front counter. It says if people have any questions about fines they can call 0800 4FINES or go to their local court.
