Ko te tatau o te motuka hei whakarato i te urunga ki te waka mā te taraiwa me ngā pāhihi, me te wehe i te pokanoa i waho o te motuka, hei whakaiti i te pānga taha ki tētahi taumata, me te tiaki i ngā kainoho. Ko te ataahua o te motuka e pā ana ki te āhua o te tatau. Ko te kounga o te tatau e whakaatahia ana i roto i te mahi ārai-tukituki o te tatau, te mahi hiri o te tatau, te ngāwari o te whakatuwhera me te kati i te tatau, me ētahi atu tohu o te whakamahinga o ngā mahi. He mea tino nui te ātete ki te tukinga, nā te mea ina pā te taha o te waka, he poto rawa te tawhiti ārai, ā, he ngāwari ki te whara i ngā kainoho o te waka.
