Every student at Westlake Girls High School belongs to one of five houses named after significant local areas. The house colours – black, gold, red, blue and green – reflect the Olympic rings to encourage the pursuit of excellence and relate to the meaning of each of the house names. The house system offers leadership opportunities for senior students and allows all students to feel connected to a smaller community within the school. Throughout the year the houses compete in a variety of events and select a house charity to support.

Each House has a House Captain, Academic Prefect, Arts Prefect, Cultural Prefect, Environmental Prefect, Service Prefect, Sports Prefect, Tuakana Co-ordinator – and a group of Tuākana students overseeing the Junior School. We also have several International Prefects. In addition, our Head Prefect and Deputy Head Prefect are highly visible leaders and role models for their fellow students at assemblies and school events. They also fulfil responsibilities in the wider school community.
