In April, the drummer entered a guilty plea to one count of threatening to kill, possession of methamphetamine and possession of cannabis. Last week, the Judge banned Rudd from taking any drugs not prescribed to him and he will be monitored 24 hours a day during his home detention, which he'll serve at his waterfront Tauranga mansion.

Now, the New Zealand Herald reports Rudd's lawyer has lodged an appeal to the July 9 sentencing. A series of significant new insights around the case emerged from the sentencing hearing, including:

• Rudd has been meeting one-on-one with a specialist psychiatrist but authorities have remained concerned about his behaviour. It emerged ESR results showed Rudd had tested positive for cannabis in a test in December.

• Rudd has reconciled with his would-be victim and agreed to pay him a substantial sum of money in reparation - the Herald can not reveal the amount for legal reasons. Mr Tuck told the court a process that had "started badly" had "ended beautifully".

• Rudd's lawyer claimed that a conviction would result in losses in the tens of millions of dollars that would have came from being able to tour with AC/DC. The Crown cast doubt on this assertion, pointing out there was no direct evidence that Rudd was still a member of the band.
