Tikanga o te mahi whakairo: ka taea hoki te whakairo ki te whakaahua matū, na roto i te hanga pereti whakakitenga me te whakawhanaketanga, ka tangohia te kiriata whakamarumaru o te waahi tarai, a ko te waahanga o te kowiri tira ka tangohia mai i te kiriata whakamarumaru ka pa atu ki te otinga matū e whakamahia ana mo te tarai, kia tutuki ai te painga o te whakakore me te pirau, te hanga i te ahua o te kowiri me te porowhita, te whakakikorua ranei.

Te rere o te tukanga tarai:

Tikanga whakakitenga: te whakatuwhera rauemi → te horoi rawa → te whakamaroke → te raima → te whakamaroke whakamaroke → te whakawhanake → te whakamaroke → te tarai → te tihorea

Tā mata: rauemi – pereti horoi – tā mata – whakairo – kiriata

Ka kitea nga painga o te tarai. Ka taea e ia te mahi machining hianga i runga i te mata whakarewa, hoatu i te mata whakarewa pānga motuhake. Engari anake te drawback ko tatou e āwangawanga e pā ana ki te raruraru o te otinga o tenei ahua o te wai ha'iriiri he mea ki te tinana tangata he kino te taiao ranei, engari iti hanga ake kua kua kii, me te rauemi me te tukatuka o te kowiri tira i muri i tetahi atu tukanga muri-tukatuka, maimoatanga mata o te kowiri tira e kore e noho kino te tinana o te mata o te tinana o te tangata.
