Normally it is the Court that hands out a sentence (we presume) after a fair trial...

However the Parole Act 2002 Section 18 (2) states that an additional six months sentence can be imposed after the Sentence imposed by the Court has concluded?

Conditions imposed by the parole board can be quite restrictive and amount to an additional sentence .... one example is of a person instructed to live in (Dunedin) a city unfamiliar to that person, regular reporting to parole officer, and of course that bracelet which tracks ones every move.... (all resembling additional sentences? rather than merely conditions of release)

My understanding of the English word "Parole" is....

"the temporary or permanent release of a prisoner before the expiry of a sentence, on the promise of good behaviour."

Its seems strange then that the "Parole Act 2002" has been so misused as to extend the expiry of a sentence without trial ...... or have I got that wrong?

There may well be a need to extend the supervision of some persons for the purposes of reintegration but surely provision for "that" should be contained within the sentence handed out by the court rather than an act which most would presume should no longer have any teeth at the end of the sentence handed out by the court.
