OD me te matotoru o te pakitara
Te roa me te rahinga
Ngā whakaritenga paninga (mēnā he mea kei roto)
Tauranga ūnga
Tukuna mai tāu patai inaianei, ā, ka whakautu mātou i roto i ngā hāora 24 me tētahi whakatau utu whakataetae.
Q: Ka taea e koe te tautoko i ngā kaupapa tere, ngā kaupapa nui rānei?
Āe. He kaha tō mātou kaha whakaputa mō ngā ota nui me te tuku kaupapa.
Mō ngā kaupapa tere, ka taea e mātou te arotau i te whakaritenga whakaputa kia tutuki ai ngā wā kati poto.
Whakapā mai ki a mātou me te rārangi wā mō tō kaupapa mō te tautoko matua.
P: Me pēhea taku whiriwhiri i te PSL1, i te PSL2 rānei mō taku kaupapa?
A: He pai te PSL1 mō ngā tono paipa whānui, ko te PSL2 ia e taunakitia ana mō ngā kaupapa pūngao pēhanga teitei, ngā kaupapa pūngao tai, me ngā kaupapa pūngao nui.
Mena kāore koe i te tino mōhio, ka taea e tā mātou tīma hangarau te taunaki i ngā whakaritenga tika i runga i ngā āhuatanga o tō kaupapa.
