whakamaumau
1. (verb) (-tia) to waste, squander.
Ki taku whakaaro he ritenga pai ia mō ngā Māori, nō te mea he ritenga tiaki kai ia, he ritenga whakaputa mai i te moni, he whakawhiwhi ki te rawa, ehara i te ritenga whakamaumau kai, whakamāngere i te tangata (TWMNT 21/3/1876). / In my opinion it would be a good system for the Māori to adopt, because it's a practice that saves food, it brings in money, and increases wealth, and it is a system that does not waste food or make a person lazy.
