Whakaahuatanga hoahoa hanganga rerekē e toru
Tauhou 1: Kei muri i te pou nohoanga te kakau takirere kia tino piri ai te hiri huri noa i te nohoanga katoa.
Tauhou 2: Ko te rārangi pokapū o te rakau takirere e peka ke ana i te paipa me te rārangi pokapū takirere, e tiakina ana mai i te pokanoa o te whakatuwheratanga me te katinga o te takirere.
Tauhou 3: Ka peka ke te kakau kōne nohoanga mai i te rārangi pokapū o te kakau takirere, ka whakakore i te waku i te wā e kati ana, e whakatuwhera ana hoki, ā, ka whakarato i te hiri pēhanga ōrite huri noa i te nohoanga katoa.
✧ E toru ngā painga o te takirere pūrerehua rerekē
1. Kei muri i te rakau pereti takirere te pou takirere, e āhei ai te hiri ki te takai me te pā ki te nohoanga katoa.
2. ka peka ke te raina o te pou takirere mai i te paipa me te raina takirere, e tiakina ana mai i te pokanoa o te whakatuwheratanga me te katinga o te takirere
3. Ka peka ke te tuaka o te koeko nohoanga mai i te rārangi takirere hei whakakore i te waku i te wā e kati ana, e whakatuwhera ana hoki, kia tutuki ai he hiri pēhanga ōrite huri noa i te nohoanga katoa.
✧ Ngā Painga o te Hononga Wafer Rerewē Pūrerehua Toru-Whakataurite
I te wā e whakatuwheratia ana, e kati ana hoki te takirere porowhita maitai hanga, nā te mea he iti ake te waku i waenga i te kōpae me te mata hiri o te tinana takirere i tērā o te takirere kuaha, ka ātete ki te kakahu.
He poto noa te whiu whakatuwheratanga, te whiu kati rānei o te kakau takirere, ā, he tino pono te mahi tapahi, ā, nā te mea he rite te huringa o te putanga nohoanga takirere ki te whiu o te kōpae takirere, he tino pai mō te whakatikatika i te tere rere. Nō reira, he tino pai tēnei momo takirere mō te tapahi, te whakahaere rānei me te whakawhāiti.
