āhuatanga hua
1.Ko te whakarea parenga he rite ki tera o te roa o te paipa;
2. He hanganga ngawari, he iti te rahi me te taimaha marama;
3.I tenei wa, kei te whakamahia nuitia te kirihou o te mata hiri o te paera poroporo me te pai o te mahi hiri, a kua whakamahia nuitia i roto i te punaha korehau;
4.He ngawari te whakahaere, te whakatuwhera me te kati tere, mai i te tuwhera ki te kati katoa tae noa ki te 90 ° hurihanga, he pai mo te mana mamao;
5. He ngawari te tiaki, te hanganga ngawari o te paera poroporo, te mowhiti hiri whakaneke, te ngawari te whakakore me te whakakapi;
6. Ka tino whakatuwheratia, ka kati ranei te paera, ka wehea te mata hiri o te poi me te nohoanga o te paera mai i te reo, a ka kore te paheketanga o te mata hiri o te paera ka pahemo te reo;
7.He maha nga momo tono, mai i te iti te diameter ki te maha o nga mitamano, ki etahi mita, mai i te korehau teitei ki te pehanga teitei. Ina huri te poi ki te 90 nga nekehanga, me porohita te kokoru me te putanga o te poi, kia kore ai te rere.
