The son of the Maori King will be back before the court next week.
Last month, Korotangi Paki, 19, was let off charges of burglary, theft and drink driving by Judge Philippa Cunningham after his defence counsel successfully argued a conviction would ruin his chances of succeeding to the throne.
A couple of weeks later Crown Law confirmed it would appeal against the decision to the High Court.
The hearing on August 29 is likely to be brief, as lawyers look to set a suitable date for the appeal to be heard.
Paki's attendance at the hearing is not compulsory and his partner is due to give birth just days later.
