Kei tua atu i te Whakamahana me te Whakamatao Taketake: Te Mātāpono Matua o te Whakawhiti Wera

I tōna māmā noa iho, hewhakawhiti weraka āwhina i te whakawhiti wera mai i tētahi wai (wai, hau rānei) ki tētahi atu. Ka rere ēnei wai, ka wehea e tētahi pakitara totoka (he mea whakarewa te nuinga), ka ārai i te poke, me te tuku hoki i te pūngao wera kia puta. He whānui tēnei tukanga:

1. Te Whakamatao: Te tango i te wera kāore e hiahiatia ana mai i te wai tukanga (hei tauira, te whakamatao i te hinu whakahinuhinu i roto i te miihini, te whakamatao i te putanga o te tauhohenga i roto i te tipu matū).
2. Te whakamahana: Te tāpiri i te wera e tika ana ki te wai (hei tauira, te whakamahana i te wai whāngai i roto i te pōro hiko, te whakamahana i ngā awa tukanga i mua i te tauhohenga).
3. Te Whakatōtō: Te huri i te mamaoa hei wai mā te tango i tōna wera huna (hei tauira, te mamaoa whakatōtō i te whakaputa hiko, te hauhautanga i ngā waeine AC).
4. Te mimiti: Te huri i te wai hei mamaoa mā te tāpiri wera (hei tauira, te whakaputa mamaoa, te whakatōtō i ngā otinga i roto i te tukatuka kai).
5. Te Whakaora Wera: Te hopu i te wera para mai i tētahi awa hei whakamahana i tētahi atu, ka tino whakanui ake i te pai o te whakamahinga o te pūngao me te whakaiti i ngā utu wahie me ngā tukunga.
