Teihana Mahi Whakarewa Rōpoti Tuitui-Rua Matua Aunoa Katoa
Ko te nuinga o te wā, ka whakamahia tēnei teihana mahi hei whakatinana i te whakarewa aunoa o te hononga o roto o te whitiki matua o te whitiki takirua. I muri i te whāngai ā-ringa i waenganui i ngā ahunga whakapae me te poutū, ka hurihia te wahi mahi ki te ±90° e te mīhini huri waipēhi ringa-L, ā, ka rapu aunoa te karetao i te tūranga whakarewa. Kua tino pai ake te kounga o te hononga whakarewa, ā, kua pai ake te whai huatanga o te whakarewa o ngā wāhanga hanganga kerēni, inā koa kua whakaatuhia he painga nui o te whakarewa o te hononga whakarewa o roto. He mehua anō hoki tēnei o Henan Mine hei tiaki i ngā kaimahi me te whakapai ake i te kounga me te whai huatanga.
