Ko te keri i roto i nga hanganga me nga mea wetewete, kaore ano kia whakakotahi ka puta mai nga raru penei i te kohao poka ka ana ki roto, ka tiangi ranei.Me pehea te karo i enei raruraru?I roto i nga tau o te parakatihi me te rangahau, i whakawhanakehia e matou te punaha putunga tuuturu me te moka mowhiti mo nga tono whanui.Ma te pai o te urunga, ka eke te punaha ki te 100 mita te roa, ka taea hoki te whakamahi mo te puranga turanga.
Ka whakamahia ki te hanga taumahatanga me nga ahuatanga topographic matatini me nga ahuatanga o te whenua, penei i te kirikiri, te hanganga kapiti, te toka, te whakangao whenua me etahi atu.
