He mate ka horapa haere mai i tētahi tangata ki tangata kē, mai i tētahi rauropi ki rauropi kē. Mā te whakapā ā-tinana, mā te kawea rā runga i te hau takiwā rānei e whakawhitia ai ēnei momo mate. Hei tauira o te mate rere, ko te kohi, ko te koroputaputa me te mate ārai-kore. Kāore he rerekētanga o te mate rere me te mate horapa, engari e tino aro ana te mate rere ki te tangata e pāngia ana ki taua mate, ā, e aro ana te mate horapa ki te moroiti e kawe ana i te mate.
