Whakaahuatanga:

1. He iti te utu mō te maimoatanga: He iti ake te utu mō te whakawerawera i te peita wera i ērā atu paninga peita.

2. Pakari: Ko ngā āhuatanga o te maitai koki whakarewa wera-tuku ko te kanapa o te mata, te paparanga konutea ōrite, kāore he turuturu, kāore he paheke-maturuturu, he piri kaha, he ātete ki te waikura. I roto i te taiao tāone iti, ka taea te pupuri i te matotoru paerewa o te maitai whakarewa wera-tuku ātete-waikura mō te neke atu i te 50 tau me te kore e whakatika; i roto i ngā rohe tāone nui, i ngā takutai moana rānei, ka taea te pupuri i te matotoru paerewa o te paparanga maitai whakarewa wera-tuku ātete-waikura mō te 20 tau. Kāore e hiahiatia kia whakatikahia.

3. He pai te pono: Ka honoa te paparanga piauau ki te maitai, ka noho hei wāhanga o te mata maitai, nō reira he pono ake te roa o te paninga.

4. He pakari te paninga: ka hangaia e te paparanga piauau he hanganga whakarewa motuhake, ka taea te tu atu i ngā kino miihini i te wā e kawe ana, e whakamahia ana hoki.

5. Tiakitanga whānui: Ka taea te whakakikorua i ia wāhanga o te wāhanga whakakikoruatia, ahakoa i roto i te pouri, ka taea te tiaki katoa i te kokonga koi me te wāhi huna;

6. He penapena wā, he penapena mahi: he tere ake te tukanga whakapūmau i ētahi atu tikanga hanga paninga, ā, ka taea te karo i te wā e hiahiatia ana mō te peita i te papa i muri i te tāutanga.
