He mea tino nui te whiriwhiri i ngā mata keri kohatu tika i mua i te tīmatanga o te kaupapa.
Ka taea e te pakeke o ngā toka te ngohengohe, te pakeke waenga, te pakeke tino pakeke rānei, ka rerekē pea te pakeke o tētahi momo toka, hei tauira, kei roto i te kōhatu papatahi, i te kirikiri kirikiri, te kōhatu papatahi ngohengohe, te kōhatu papatahi waenga me te kōhatu papatahi pakeke, te kirikiri kirikiri waenga me te kirikiri kirikiri pakeke, me ētahi atu.
I roto i te kaupapa keri,Te Rawhiti Tawhitihe 15 tau te roa, ā, neke atu i te 30 whenua te wheako ratonga ki te whakarato i ngā mata keri me ngā wairua keri matatau mō ngā tono maha. Kei roto i te tonote keri waro, te keri parahi, te rino, te kourame ērā atu anō. Ka taea te whakarite i ngā momo mata keri kia rite ki ngā hanganga toka rerekē nā te mea kei a mātou ā mātou akeAPI me te ISOwheketere whaimana o ngā mata keri. Ka taea e mātou te tuku i te otinga a tā mātou miihini ina taea e koe te whakarato i ngā tikanga motuhake, pēnei i tete pakeke o ngā toka, ngā momo taputapu keri, te tere hurihuri, te taumaha o te mata me te taipana.
