The water shortage in Auckland shows no signs of letting up - and city's water supplier, Watercare, could spend up to $180 million on finding different water sources.
This could include desalinating seawater.

And experts say dry conditions are expected to continue through to the end of this month.
Watercare chief executive Raveen Jaduram talks to Karyn Hay.
