I roto i tēnei tuhinga, ka tūhuratia e mātou tengā mātāpono mahi, momo(tae atu kingā takirere pōro 3-ara kowiri tira, Momo Y, Momo L, meMomo T), ngā tono, mengā paingao ēnei takirere.
Te Mātāpono Mahi o tētahiTakirere Pōro 3-Ara
Ko te takirere pōro ara-toru he pōro tuwhera, he porotaka, he kotahi, he rua rānei ngā putanga (kōhao) me ngā hononga paipa e toru. Mā te huri ā-ringa i te pōro, mā te whakamahi rānei i tētahi pūwhakaoho, ka hurihia te ara rere. I runga i te hoahoa o te takirere, ka taea e ia:
- Whakarerekētia te rerei waenganui i ngā putanga e rua.
- Whakaranua ngā waimai i ngā tomokanga e rua ki te putanga kotahi.
- Whakamutua te reretino.
Ko te tūranga o te pōro te mea e whakatau ana i te ahunga o te rere. Hei tauira, mā te hurihanga 90-tohu ka taea te whakawhiti i te rere mai i tētahi putanga ki tētahi atu, mā te hurihanga 180-tohu ka taea te aukati i te rere katoa.
