Te mārama ki ngā Tautoko Pūpahi Nui me ō rātou Āhua Mahi

He aha ngā Tautoko Pūpahi Nui, me pēhea rātou e mahi nei?

Ko ngā tautoko papa kaha e āwhina ana i ngā papa kaha e toa ana i te wā e huihui ana rātou ki te tōaitanga o te rere o te wā, engari he tino pāpaku hoki te āhua o te noho (te papa kaha e utu ana) e takoto ana ki runga i te mea taea e whakarereke tētahi e ringa anō rānei e tētahi taputapu. Ina hiahiatia ana e ngā inihua te tōaitanga o te papa kaha, ka hurihia te pāpaku, ka whakauru rānei ki te pāpaku pātata kia tōtika te āhua. Kātahi ka āwhina i ngā take pērā i te papa kaha e whānui ake ana ina wera, e rere ana i ngā kōaru, ina tāutuhia ana he iti noa te wehe. I tētahi pūrongo mai i te Rōpū Piping Systems i te tau 2023 i kii mai ngā tautoko papa kaha hōu ake e taea ana te kawenga e 15 miriona pauna te rahi, kāore i te nui te wehe, e toa ana i te tōtika o te rahi o te rima ōrau o te ina.

Ngā Tino Tāwāhi: Te Whakarereke i te Kāwanatanga, Te Tōtika, me te Otinga o te Pūnaha

E toru ngā tāwāhi matua e whakamārama ana i ngā tautoko papa kaha e āwhina ana:
