1j65 Rau/pereti koranu aukume ngohengohe FeNi65Kei roto i te papa aukume ngoikore ngā koranu aukume ngohengohe, he nui te uruhanga me te iti o te kaha akiaki o ngā koranu. He whānuitia te whakamahinga o tēnei momo koranu i roto i ngā hikohiko reo irirangi, ngā taputapu me ngā mita tika, te mana mamao me te pūnaha whakahaere aunoa, ko te nuinga o te whakamahinga o te whakakotahitanga mō te hurihanga pūngao me te tukatuka mōhiohio, he mea nui ngā āhuatanga e rua i roto i te ōhanga ā-motu. He kupu whakataki ki te
I raro i te mahi a te aukume ngāwari, ka ngaro te papa aukume o waho o te koranu aukume ngohengohe, ka memeha haere te kaha o te aukume me ngā koranu aukume i muri i te tango i te papa aukume. 1j65 Te hanganga matū
