Bail was not sought by the 15-year-old who was remanded in residential care while the 18-year-old was remanded in custody by consent. All five accused will reappear in the Whakatane Youth Court on January 17.
Judge Wills granted the 17- and 18-year-olds interim name suppression on the grounds of identification while the three younger accused cannot be named for legal reasons.
During the lengthy appearances, Judge Wills described the injuries received by the German pair. The woman was left with a fractured eye socket, a broken nose, a gash to the forehead, a fractured arm and bruises and scrapes while the man lost some teeth.
Meanwhile, the tourists are spending time in the Bay of Plenty with friends. Detective Senior Sergeant Greg Standen said young couple had shown tremendous fortitude to bounce back from the incident.
"When we spoke to them today they said they were happy that the whole of New Zealand had given them so much support including letters after this incident and this was very helpful to them to receive this amount of support."
Police are not looking for anyone else in relation to the incident.
