Ko ngā rauemi te tūāpapa me te matapae o te whanaketanga ōhanga me te pāpori ā-motu. I roto i te tukanga o te hauhake rauemi, te tango, te whakarite, te whakaputa, te tukatuka, te kawe, te whakamahi me te whakakorenga, i tetahi taha, ka whakatairanga i te whanaketanga pāpori me te ōhanga me te ahunga whakamua o te ao tangata, i tetahi taha. He nui hoki te kaha me ngā rauemi e pau ana, ā, he nui te hau para, te wai para me ngā toenga para e tukuna ana, e whakapoke ana i te taiao noho o te tangata. E whakaatu ana ngā tatauranga maha, mai i te tātaritanga o te kiato whanaunga o te kaha me te whakamahinga rauemi me te pūtake o te parahanga taiao, ko ngā rauemi me ō rātou hanga tetahi o ngā kawenga matua e hua ai te korenga o te kaha, te whakamahinga rauemi nui me te mimiti.
