Ngā takirere keti e whakamahia ana hei aukati i te rere o ngā wai, kaua hei whakahaere i te rere. Ina tuwhera katoa, kāore he arai o te takirere kēti noa i te ara rere, ka iti rawa te ātete rere. Ko te rahi o te ara rere tuwhera ka rerekē i te nuinga o te wā i te mea ka nekehia te kēti. Ko te tikanga o tēnei kāore te tere rere e rerekē ōrite me te haere o te kakau. I runga i te hanganga, ka taea e te kēti tuwhera wāhanga te wiri i te rere o te wai.
