"It's crazy that there are dry river beds but green paddocks and sprinklers going all year round. It's become a real problem."
Ms Te Maari said Gail Tipa, of Ngai Tahu, spoke at the hui about how representatives from the different groups "could measure the health of water from a cultural perspective".
The group was told cultural indicators could include metrics such as the variety and number of fish species, the abundance of aquatic insects, and the preponderance of slime in Wairarapa rivers and waterways.
"The hui also included a field trip around Wairarapa Moana [Lake Wairarapa] where council staff had caught different varieties of native and pest fish for us to look at," she said.
"It was all very exciting because we are seeing a movement of Maori taking more of a role in the management of this precious resource."
