The Council is temporarily treating Christchurch's drinking water with chlorine while it upgrades the below ground well heads.
The Council maintains flag poles in the following locations and are maintained quarterly.
No flag should fly higher than the New Zealand Flag. When the New Zealand flag is at half mast, all other flags must be removed. These flags are lowered to half mast in times of mourning.
Flags on Government buildings should be flown at half-mast when directed by the Chief Executive of the Ministry for Culture and Heritage.
There is no authority over flags from private companies or businesses.
