    whakaahuatanga-hua1

    Me tu te paipa i te whakamātautau waipū, me te kore e turuturu mā te hononga whakarewa, mā te tinana paipa rānei.
    Kāore e hiahiatia kia whakamātauria ngā hononga mā te whakamahi i te wai ā-pūmau, ki te mea kua whakamātauria angitu ngā wāhanga o te paipa i whakamahia hei tohu i ngā hononga mā te whakamahi i te wai ā-pūmau i mua i te mahi honohono.

    Te Whai Aroturuki:
    Mō ngā paipa PSL 1, me whakatū e te kaihanga, ā, me whai i ngā tikanga kua tuhia mō te tiaki:
    Ko te tuakiri wera kia oti rā anō ia whakamātautau matū e pā ana, kia whakaaturia rā anō te tutuki i ngā whakaritenga kua tohua.
    Ko te tuakiri o te wae whakamātautau kia oti rā anō ia whakamātautau ā-ringa e pā ana, kia whakaaturia rā anō te tutuki i ngā whakaritenga kua tohua.
    Mō ngā paipa PSL 2, me whakatū e te kaihanga, ā, me whai i ngā tikanga kua tuhia hei pupuri i te tuakiri wera me te tuakiri waeine whakamātautau mō taua paipa. Me whakarato ēnei tikanga i ngā huarahi hei whai i te roa o te paipa ki te waeine whakamātautau tika me ngā hua whakamātautau matū e pā ana.
