[1] Mr Wilson, on 9 May this year, Campbell J entered conviction against you on your guilty plea to the murder of Betty Maree Paparoa. I know my words aren’t worth very much but I offer the Court’s condolences to Ms Paparoa’s survivors.

[2] Mr Wilson, I am now to sentence you for that offending. In doing so, I must accept as proven all facts essential to your guilty plea.1 For your murder of Ms Paparoa, I must sentence you to imprisonment for life, unless the wider circumstances of your offending made that manifestly unjust.2

[3] If sentencing you to life imprisonment, I then must impose a minimum period of imprisonment before you may even be eligible for parole. That must be a period of at least ten years’ imprisonment,3 or at least 17 years if I find Ms Paparoa’s murder to have been in specified exceptional circumstances; the latter period, again, unless manifestly unjust.4

[4] If you are then to be released depends entirely on you satisfying the Parole Board, if released, you do not pose an undue risk to the safety of the community.5 If then released, you will be subject to release conditions for the rest of your life.6

[5] I have listened and read what counsel have had to say, both for you and for the Crown. Neither suggest life imprisonment would be manifestly unjust in your circumstances. The Crown recommends a starting point minimum period of imprisonment of 16½–17 years but acknowledges then an end sentence of at least 17 years would be manifestly unjust, as not permitting any discount for your guilty plea. Your counsel suggests your offending was not so heightened as to require at least the 17-year minimum period and recommends a minimum period of 14½–15 years’ imprisonment. I am not bound by their views; I have to come to my own decision. I must satisfy myself of the appropriate sentence for the gravity — for the seriousness
— of your offending, including your culpability — your responsibility — for it.

Your offending

[6] I need first to cover off the background to your offending, to set out in public the conduct for which I am sentencing you.

[7] After meeting as flatmates in the Waikato’s Ngāruawāhia, you and Ms Paparoa lived together for some years, most recently in Cambridge. Your relationship is said to have been volatile at times, particularly over disagreements about your shared…

Grounds of appeal

[14] The appellant contends that the primary judge erred in finding that the respondent had discharged the onus of establishing the matters required under the relevant provision.

[15] It was submitted that his Honour failed to give adequate weight to the evidence of the second witness, and that the findings of fact were not reasonably open on the material before the Court.

[16] The respondent, for its part, submits that no error is disclosed, and that the conclusions reached were well within the range of outcomes available to the primary judge.

Consideration

[17] It is convenient to deal first with the question of construction, as the resolution of that issue informs the remaining grounds advanced by the appellant.

[18] For the reasons that follow, we are of the view that the appeal should be allowed in part and the matter remitted for further determination.

CaseChat Overview and Summary

Aaron Nicholas Wilson stood convicted of murdering Betty Maree Paparoa, a crime for which he had pleaded guilty. The sentencing hearing was presided over by Jagose J in the High Court of New Zealand at Hamilton, where counsel for the Crown and the defendant presented their respective submissions. The central legal issue was determining the appropriate sentence for Wilson, specifically whether life imprisonment would be manifestly unjust and, if not, establishing the non-parole period. The court was required to balance the aggravating factors of the murder with any mitigating circumstances.

Jagose J commenced by acknowledging the heinous nature of the crime and the devastating impact on the victim's family. The court highlighted several aggravating factors, including the premeditated nature of the attack, the use of a weapon, the vulnerability of the victim, and the brutality of the assault. The court noted Wilson's history of family violence and his lack of remorse, which further underscored the severity of the crime. After considering the submissions from both the Crown and Wilson's counsel, the court determined that life imprisonment was the appropriate sentence. However, due to Wilson's guilty plea, the court applied a discount to the non-parole period. After careful consideration, the court set the non-parole period at 16 years, finding it to be proportionate to the gravity of the offence and Wilson's culpability.

In summary, Wilson was sentenced to life imprisonment with a non-parole period of 16 years, reflecting the court's commitment to justice, denunciation, and community protection, while also considering the mitigating effect of his guilty plea.
