Te whakarōpū mata
Mata noa (FA)
Ko te mata î ka whakaaetia kia whai koha iti me te rohe penei i te rua, nga pakaru, nga karawarawa, me etahi atu, ko te hohonu (te teitei ranei) kaore e neke atu i te haurua o te whakamarumaru o te pereti rino, engari ko te iti rawa o te matotoru o te pereti maitai me te ka whakapumautia te tira rino.
Mata teitei (FB)
Ko te mata pikinga ka whakaaetia kia whai koha o te rohe karekau e pa ki te ahua o te ahua, penei i te paku rakuraku, paku nuku, paku rua, paku tohu roera me te rereke o te tae.
Te whakamahi rauemi
Ka whakamahia te nuinga mo te hanga, te piriti, te kaipuke, nga waahanga hanganga waka, te hanga momo taputapu, nga taputapu tapahi, nga miihini me nga taputapu ine.
