Nga ahuatanga hua
1. He mea hou, he whaitake hoki i roto i te hoahoa, he ahurei te hanganga, he marama te taumaha, he tere te whakatuwhera me te kati.
2. He pai nga painga o te puera rerehua mo te waa whakahaere iti, he watea te mahi me te penapena mahi mohio.
3. Te whakamahi i nga rawa e tika ana hei whakatutuki i nga rereke rereke o te papaa iti, o te reo me te teitei me te paoho pirau.
4. Kaore he rakau hono, he pou, he aha atu, he mahi pono, he roa te ora o te ratonga, kaore e pa ki te huarahi rere o te hunga pāpāho.
