Whakatakotoranga
Ko te pahū he pepa ngongo kikorangi me te ngongo kowakawaka, kia kore ai e pakaru te pepa ngongo. 
Ko nga calandria e piki ana kei raro i te pahu. Ma tenei whakaritenga, ka whakakorehia te rohe wai mate i raro o te pahu, a he uaua te para ki runga. Ko te mutunga mai, ka pai ake te whakamahana o te rohe pawera-nui o te pahū, a ka tino whakakorehia te ahua o te pupuhi i raro o te kohua.
Ko te hoahoa tino pai o te ngongo kowakawaka e whakakaha ana i te whakawhiti wera, ka tere ake te pāmahana me te whakanui ake i te reiti mamaoa. 
Ko te hoahoa tika o te kikorangi i roto i te oumu ka whakapai ake i te ahua ngingiha, ka whakarei ake i te mahi kore o te puehu i roto, ka whakaheke i te tukunga parahanga o te kohua.
Ma te pai o te hiri, ka ngawari te whakahaere o te pouaka hau, ka taea hoki te whakarato i te hau tika. No reira, ka whakahekehia te hau i te taikaha o te hau me te whakanui ake i te pai o te waiariki.
