He mea nui te mahi a ngā taputapu porowhita nui i roto i ngā mahi moana, e tuku ana i te whai huatanga me te pakari tino pai i roto i ngā pūnaha moana. Ko ngā niho koki o ēnei taputapu, e āhei ai te whakauru maeneene me te whakaiti i te haruru, e pai ai mō ngā taiao moana e tino hira ana te pono.

Ko tētahi o ngā whakamahinga matua o ngā taputapu porowhita nui i roto i te umanga moana ko ngā pūnaha whakatere. Ka whakamahia ēnei i roto i ngā pouaka o ngā kaipuke me ngā ruku wai, ka huri i te mana miihini hei kaha hurihuri e hiahiatia ana hei whakatere i ngā kaipuke i roto i te wai. Ko te kaha o ngā taputapu porowhita ki te whakahaere i ngā kawenga teitei me te pupuri i te mahi maeneene ka whakarei ake i te mahi whānui me te pono o ēnei kaipuke moana.

Hei tāpiritanga, he maha ngā wā ka kitea ngā taputapu porowhita nunui i roto i ngā winihi me ngā hiki, he mea nui mō ngā mahi taunga me te whakahaere utanga. Nā te hoahoa pakari ka taea e rātou te whakahaere i ngā kawenga taumaha me te ātete ki te pakaru, he mea nui tēnei i roto i ngā āhuatanga moana kino. Mā tēnei pono ka whakaitihia te wā kore mahi me ngā utu tiaki, ka waiho hei whiringa pai mō ngā kaihanga kaipuke me ngā kaiwhakahaere.

I roto i te horopaki o ngā taputapu keri moana, he mea nui ngā taputapu porowhita nui mō ngā mīhini maha, tae atu ki ngā taputapu keri me te hiki. Mā te whai huatanga o ēnei taputapu ka pai ake te tukanga tango, ka whakaitihia te whakapaunga pūngao me te whakanui ake i te putanga.

I te nuinga o te wā, he mea nui ngā taputapu porowhita nunui i roto i te umanga moana, e tuku ana i te kaha, te whai hua, me te roa o te wā. I te whanaketanga o te hangarau, tera pea ka whānui ake tā rātou mahi, ka whakarei ake i ngā mahi moana, ka whai wāhi atu ki ngā mahi moana haumaru ake, whai hua ake.
