The operator of a popular central city well providing chlorine-free water says he will apply a charge on the service he provides.
Duncan Laing, who owns Lotus Spa, had provided fresh water for eight years after the 2010 earthquake.
A donation was previously accepted from users of the well.
However, opportunistic individuals were taking and selling the water for a profit.
About 2000 litres of water was taken from the well in one night; a major contributor to the decision to charge.
Users will be charged 25 cents for every litre after the first, which will remain free.
