"It is seldom, if ever, that Whanganui has seen so many people sworn in as Justices of the Peace on one day," he said.
"I have been conducting these ceremonies for over seven years now and certainly it is the most I have had the privilege to acknowledge."
The Judge said that the office of the Justice of the Peace is of great antiquity.
There have been references to the office since the statute of King Edward III of England in 1361.
In those days each country had a Lord and three or four of the most worthy men assigned to keep the peace.
They would pursue, arrest and chastise offenders and rioters.
"I am delighted to note that today there are four women being sworn in. That is helping to tidy up a ledger that was at zero up until 1926," Judge Matheson said.
"New Zealand came into the real world - not that long ago really - by acknowledging females in the Justices of the Peace process."
Despite the decline in physical demands, the role of the Justice of the Peace is just as important in today's society.
Justices of the Peace take declarations and affidavits, witness documents and may even be required to attend hearings or trials.
The Judge said it never ceases to amaze him that they do it for no financial reward.
"Unfortunately being a JP doesn't add to the pay scale at all and what you are offering to do is for nothing, but your love for the community.
"With these oaths having been duly administered, you are now able to take up and exercise the responsibilities and privileges of a Justice of the Peace of New Zealand."
