Ko tā mātou tauira 450x71 noangā ara kerihei whakamahi mā ngā raro o ngā mīhini i hangaia mō te whakahaere i runga i ngā ara rapa. Kāore ngā ara rapa tuku iho e pā ki te whakarewa o ngā roera o te taputapu i te wā e whakahaerehia ana. Mēnā kāore he pā, ka pai ake te whakamarie o te kaiwhakahaere. Ko tētahi atu painga o ngā ara rapa tuku iho ko te pā o te roera taputapu taumaha ka puta ANAKE i te wā e whakahāngaitia ana ngā ara rapa tuku iho hei ārai i te hekenga o te roera.

Tō mātoungā ara keri itihe mea hanga mai i ngā matū rapa motuhake e ātete ana ki te tapahi me te haehae. He hononga maitai katoa ā mātou ara, kua hangaia kia rite ki ngā whakaritenga aratohu tika kia uru ki tō mīhini, kia maeneene ai te mahi a ngā taputapu. He mea hanga-taka ngā whakaurunga maitai, ā, kua toua ki roto i tētahi kāpia here motuhake. Mā te toua i ngā whakaurunga maitai, kaua ki te paraihe ki te kāpia, ka kaha ake te here i roto; mā tēnei ka roa ake te ara.

Me pēhea te whakaū i te rahi o te ara rapa whakakapinga

Ko te tikanga, he tānga kei roto i te ara me ngā mōhiohio mō tōna rahi. Ki te kore e kitea e koe te tohu mō te rahi, ka taea e koe te tiki i tētahi whakatau tata mā te piri ki te paerewa ahumahi me te whai i ngā mahi kua whakahuatia i raro nei:

Inehia te teitei o te koki, arā, te tawhiti mai i waenganui ki waenganui i ngā pūmau taraiwa, ki ngā mirimita.

Inehia tōna whānui i roto i ngā mirimita.

Tatauhia te tapeke o ngā hononga, e mōhiotia ana ko ngā niho, ko ngā pūmau taraiwa rānei, i roto i tō mīhini.
Ko te tauira paerewa ahumahi hei ine i te rahi ko:

Rahi Ara Rapa = Teitei (mm) x Whānui (mm) x Tau o ngā Hononga
