Each year Gisborne Boys’ High School offers many cultural opportunities to its students. These primarily run as extracurricular activities and students meet with staff on a regular basis during lunchtimes or after school.
Several competitions and events serve as a focus for GBHS cultural activities.

Debating
GBHS is represented at the Cultural Super 8 competition with both Junior (Year 9/10) and Senior (Year 11-13) debating teams. In the past students have also competed in the Russell McVeagh Regional Debating competition. The annual staff versus student debate is a highlight on the school calendar.
