On arrival at WBHS, each boy is assigned to a whānau group. All Carruth House boarders are assigned to Carruth whānau (along with some day boys). Within each Whānau there are up to ten vertical form groups or classes, each with its own whānau teacher. A very hotly contested Inter-Whānau competition takes place throughout the year. Swimming, Athletics, Basketball, Indoor Hockey, 7-aside Rugby, Cross-country, Music, Speeches, Inter-whānau Quiz, Singing, Tennis, Haka and Academic endeavour all contribute to the overall points for each whānau.
