Hastings Boys' High School has introduced the wearing of lavalava as part of the dress code for their Pacific Island students.
The traditional garment is part of the dress uniform for special occasions.
Principal Robert Sturch said the initiative had been requested by the Samoan leaders of the school.
"They found that there were five crucial ceremonies during the year which they would be able to present themselves in a culturally appropriate manner."
The Pasifika leaders would be in the traditional clothing next Thursday for senior prizegiving, where they were being acknowledged for academic achievement and contribution to the school.
