Woman pleaded guilty to owning pet that attacked and caused serious injury
In a proceeding arising from a dog attack, New Zealand’s Court of Appeal upheld an assessment of the gravity of the offending as medium, given the victim impact and the pet owner’s prior knowledge of the risk of an attack.
In Tupa'i v R [2026] NZCA 23, the appellant’s dog, under the care of her then 15-year-old son, bit a 70-year-old woman in New Lynn, Auckland, on 27 October 2023. The appellant referred the pet to Animal Control. The family euthanised the dog at home.
The appellant pleaded guilty to owning a dog that attacked a person and caused serious injury under s 58(a) of the Dog Control Act 1996, an offence punishable by the destruction of the dog, as well as a maximum three years’ imprisonment sentence and/or a $20,000 fine.
The appellant applied for a discharge without conviction.
Given the appellant’s unblemished record, the judge set a starting point of six months’ imprisonment, at the lower end of the six-to-nine-month range. The judge made a downward adjustment of 10 percent for her guilty plea, plus 15 percent for her remorse and assistance of the victim.
The judge declined to grant a discharge without conviction. She accepted that the appellant was a model citizen without prior convictions and with excellent work in the community and as a teacher.
The judge deemed the offending of medium gravity due to the deep wound, which required days in hospital, and the appellant’s previous experience when another one of her dogs attacked someone.
The judge explained that the conviction’s consequences would not outweigh the charge’s seriousness, as a conviction would not likely negatively impact the appellant’s teaching career or reflect adversely on her character.
The appellant appealed the denial of a discharge without conviction. She applied to adduce fresh evidence consisting of affidavits from herself and her son.
The appellant’s counsel submitted that the additional evidence gave context for the conviction’s effects, including the temporary disqualification from owning a dog, on the teenage son and the rest of the family.
The Crown opposed the appeal and the fresh evidence application.
The Court of Appeal of New Zealand granted the application to submit fresh evidence. The appeal court admitted and considered the affidavits, given their potential relevance to the appeal’s primary focus.
However, the appeal court dismissed the appeal of the denial of a discharge without conviction.
The appeal court acknowledged that the appellant and her son offered significant assistance to the victim and self-reported the dog to Animal Control after the attack.
However, the appeal court noted that the appellant had previously owned a dog that attacked somebody else, understood the implications, and arranged for the family to train in handling the dogs.
In this case, the appeal court pointed out that the dog involved was of the same breed and was unmuzzled while a teenager was walking it in an urban area, where it was able to attack someone viciously.
The appeal court determined that the attack caused serious injuries, specifically a 10–15 centimetre wound, leading to the victim staying in hospital for two days, undergoing surgery, and developing a fear of dogs.
Regarding the conviction’s consequences, the appeal court found its implications for the appellant’s visa-free travel or her exposure to the Teaching Council’s registration review process proportionate to the gravity of the offending.
The appeal court said the administrative inconvenience alone was not a disproportionate effect. The appeal court added that the conviction would not likely impact assessments of the appellant’s character or be a relevant consideration for foreign governments or the Teaching Council.
Lastly, the appeal court held that the conviction’s difficult and upsetting impacts on the family were also not disproportionate consequences of the conviction.
