The new technology, being used in Mt Eden, Waikeria, Christchurch Men's and Whanganui Prisons and installed in Auckland, Hamilton, and Manukau District Courts, had already saved more than 8000 external prisoner trips to and from courts, said Mrs Tolley.
About 40,000 people in prisons on remand make court appearances across the country each year, and the new technology is expected to be used in a large number of those cases.
Mr Burrows said the cost to introduce the links to Tauranga Court is commercially sensitive because it will go out to tender, but the nationwide budget for the two-year rollout expansion plan was $27.8 million, with connected courts able to link with connected prisons anywhere in the country.
He said the Government's drive to modernise the court system was about using technology to deliver court services in ways which were better, faster, cheaper, easier and more convenient.
Tauranga's executive judge Judge Phillip Connell told the Bay of Plenty Times the changes would have huge benefits.
"On a practical level we notice as judges it saves time, energy, money and from the prisoner's viewpoint it is a more humane process and has huge implications in not only reducing costs, but improving the management of a judge's daily court workload.
Judge Connell sits in Hamilton where AVL has been used for two years.
"AVL in Hamilton has been extremely successful and its use has been steadily increasing to the point where we now use it for about 99 per cent of potential cases. People on remand often ask to be dealt with by audio-visual link, and I anticipate it will be no different in Tauranga."
Hamilton Court is also trialling the use of AVL for less serious sentencing matters.
Tauranga Crown solicitor Greg Hollister-Jones and criminal defence lawyer Paul Mabey QC welcomed the technology. Mr Hollister-Jones said he hoped it could also be used for High Court pre-trial matters reducing the need to travel out of town.
