Auckland Council’s Watercare is planning to use the river to meet the next thirty years of Auckland’s population growth, but local iwi and the Waikato Regional Council don’t want that to happen.

It means Auckland may have to look elsewhere for its water supply, and that could be costly.

The once-in-a-generation drought has unveiled some interesting things – like old railway tunnels – and some concerning things – like the tense disagreement over whether Auckland can continue taking water from the Waikato River to supply its growing population.
