Kua hurihia e ngā rama whakarewa karetao ngā mahi whakarewa mā te hangarau aunoa, ko tō rātou uara matua kei roto i te wawahi i ngā arai hangarau o te whakarewa ā-ringa:
Mō te pumau, ka whakakorea rawatia e rātou ngā rerekētanga o ngā tawhā whakarewa i puta mai i te ngenge, ā, ka pāngia e ngā rerekētanga o ngā mahi ā-ringa. Mā te pūnaha whakahaere porowhita-katia o te karetao, ka whakahaerehia te rerekētanga o ngā tawhā matua pēnei i te ngaohiko pewa, te iahiko, me te tere haere i roto i te ±5%.
Mō te whai huatanga, ka taea e rātou te mahi tonu i ngā rā katoa, i ngā rā e whitu. Ina honoa ki ngā pūnaha uta me te tango aunoa, ka taea te whakanui ake i te whakamahinga o ngā taputapu ki te neke atu i te 90%, ā, ko te kaha whakaputa kotahi-wāhanga he 3-8 ngā wā teitei ake i te kaha whakaputa ā-ringa.
