Te whakawhiti wāHe taputapu whakahaere e whakamahi ana i te mātāpono hikohiko, i te mātāpono mīhini rānei hei whakatutuki i te whakahaere whakaroa wā. He maha ōna momo, pērā i te momo whakamātao hau, te momo hiko me te momo hikohiko. Ka taea te wehewehe i ngā whakawhiti wā kia rua ngā momo: te momo whakaroa wā hikohiko me te momo whakaroa wā whakaweto-mana. He nui te awhe whakaroa o ngā whakawhiti wā whakamātao-hau (0.4 ~ 60s me 0.4 ~ 180s), he māmā te hanganga, engari he iti ake te tika.
Ina whakakahangia te koiri, ka kukumea te anga me ngā papa e te matua ka neke ki raro i te wā tonu, ka whakakā, ka whakaweto rānei i te hononga mahi wā tonu. Engari kāore e taea e te tokotoko piston me te rīwhi te whai i te anga me te hekenga, nā te mea kua honoa te pito o runga o te tokotoko piston ki te kiriuhi rapa i roto i te rūma hau, ina tīmata te tokotoko piston ki te neke ki raro i te tukunga o te puna, ka piko te kiriuhi rapa ki raro, ka angiangi te rūma hau i runga ake i te hau, ā, ka mākū te tokotoko piston, ka heke mārire. I muri i tētahi wā, ka heke te tokotoko piston ki tētahi tūranga, ka panaia te mahi whakapā whakaroa mā roto i te rīwhi, kia mutu ai te hononga pakaru hihiri, kia kati ai te hononga hihiri. Mai i te koiri whakakaha ki te wā whakapā whakaroa kia oti ai te mahi, koinei te wā whakaroa o te whakawhiti. Ka taea te whakarerekē i te roa o te wā whakaroa mā te whakarerekē i te rahi o te kōhao whakauru o te rūma hau me te tīwiri. I muri i te whakakorenga o te koiri kukume, ka ora anō te whakawhiti mā te mahi a te puna whakaora. Ka tere te tukunga o te hau mā roto i te kōhao putanga hau.
