"Tirohia" means to survey. This work explores surveying as a tool of colonial subjugation that disregards the mana of natural resources and non human others. Surveying was often used by European settlers to determine boundaries, which divided Maori land; decide where to level ground for farmlands; and to identify excavation points for precious minerals within maunga. Surveying instigates a large variety of exploitative behaviour. In these processes, the hauora of non human others is overlooked, homogenised and destroyed in the colonial endeavour for control and occupation.
