Water restrictions in Christchurch, Lyttelton and Akaroa have been lifted on Monday.
The restrictions, which have been in place since October in Christchurch and Lyttelton, and since December in Akaroa, have seen 5.67 billion litres of water saved, an overall saving of 20 per cent.
Christchurch Mayor Bob Parker says the lifting of water restrictions shows the progress that has been made in the earthquake recovery.
"Times have been tough but we are progressing well, and the fact that we can now lift water restrictions is symbolic of how far we have come over the last year," Mr Parker said.
"This is a milestone achievement for the recovery."
With the Christchurch City Council restrictions lifted, the public can now water outdoors at any time and on any day.
Sprinklers and irrigation systems can also be used, but the council is encouraging people to continue to use water wisely.
