A 16-year-old Hastings schoolboy is challenging "the lawfulness of [his] suspension" for long hair and taking the case to the High Court on Monday.
Lucan Battison was suspended from St John's College after the school required him to cut his hair as per the school's policy.
The teenager made headlines in April when he was awarded a bravery medal by Napier Mayor Bill Dalton after helping to rescue two women caught in a rip off Waipatiki Beach in January 2013.
Lucan said at the time he was not a hero and others who played even a lesser part in rescuing Analisa Tipu, 21, and Leilani Wong, 18, also deserved a medal.
His family lives at the beachside community, north of Napier.
