His lawyer, Paul Dacre, QC, on Monday told the court the accused - appearing by video link - had yet to be transferred to Auckland and there had been no time to discuss how they would proceed.
No pleas were entered and the 19-year-old has been remanded in custody.
Two of the arson charges he faces relate to the blazes at Piha, while a third is over a separate fire at central Auckland's Viaduct Event Centre.
Along with one house being evacuated and 20 others threatened, popular cafe Adey's Place was gutted by one of the fires.
About 90 firefighters and two helicopters were called out, with about seven hectares of scrub also destroyed.
