: Tohu mita

*Ka tāia te tohu i ia mita kotahi;

● He mā te tae o te tohu, engari ki te hiahiatia he tohu anō, me tā hou te tohu kōwhai ki tētahi atu tūranga.
● Ka whakaaetia te tohu roa kāore i te mārama i ētahi wā mēnā he mārama ngā tohu e rua e tata ana;
● Kua hiritia ngā pito o te taura e rua ki ngā taupoki pito ka taea te whakaiti i te wera hei ārai i te urunga o te wai.
