Hei whakatutuki i ngā hiahia rerekē o ngā kiritaki rerekē e pā ana ki te tawhiti kawe, ngā tikanga whakahaere, me ngā tahua utu, kei te tuku tā mātou kamupene i ngā momo otinga tākai ka taea te whakarite.
Mō ngā waka tawhiti poto, mō ngā kaupapa ā-whare rānei, ka whakamahia e mātou he huinga putea whatu me te papa whatu kua whakapakarihia, he mea taurite te utu whai hua me te tiaki taketake.
Mō ngā ota kaweake e hiahia ana ki ngā utanga moana tawhiti, ngā tukunga maha rānei, ka whakamahia e mātou he pūnaha putea tana + papa matotoru, he putea whatu rānei me ngā kātene kaha-teitei o te kounga kaweake, ngā pouaka rakau rānei hei tikanga tiaki tino kaha.
Ahakoa he mea nui ki te kiritaki te haumaru mōrahi, te iti o te wāhi e nohoia ana, te whai hua rānei o te utu, ka taea e mātou te whakatutuki i ō rātou hiahia mā te whānuitanga o ngā kōwhiringa takai kua whakamātauhia — e tuku pono ana i te "takai i runga i te tono, te tiakitanga kua whakaritea mō ia tuku."
I tēnei wā, ka tukuna atu e mātou he ipu 40HQ o tā mātounohoanga intalox uku
