In the this story I read was Kahawi. First there was an old lady and her mokopuna that went fishing and there was and sign that said danger because it was polluted water.When they went to go fishing there were heaps of broken stuff and there was a city that was broken and even the Sky Tower was broken too. Then when they finished looking around they started to fish.Soon when they put their little net down then they got a fish that was called Kahawi. Last of all the old lady that was with her mokopuna put the fish back into the water.
This story is trying to tell us not to pollute the water and so that we get staff to drink and not to cuck rubbish into the water.
