The waiting list for water delivery on Waiheke Island is getting so long some families need to go without water for days on end.
A hot, dry summer combined with a bump in the number of visitors over recent months is putting a strain on the system.
Locals say it's not the availability of water that's the problem - it's about the capacity that carriers have to actually deliver the water to households.
Waiheke board member Paul Walden says it's left many of the island's vulnerable residents - such as the elderly, disabled and families - in a bad place.
He says in some situations households are being left without water altogether for up to two weeks and then waiting longer for water to actually be delivered.
Paul Walden says there have been public facilities set up by the council around the island for people to get water.
