The system is based entirely on convention without any written standard. These markings are color-coded, and are painted by contractors onto the pavement. The main colors based on the convention are used in the same way as in the US: red for electricity, yellow for gas, and blue for water. However, other colors have other meanings. Green is used for telecommunication conduits. White is used as general communication between contractors; white is also used to note the details of road surface markings so that markings can be easily restored after the road construction is completed; a few telecommunication companies also use white color for their utility locations. Orange and other colors are used by local authorities to mark improvements and other details not related to utility locations. New Zealand There is no legal color code requirements for buried utilities and surface markings, however a general convention is used and encouraged by the government health and safety department - Worksafe. {| class="wikitable" |Underground Duct |Surface Marking Color |Surface Marking Letter |Utiltiy |- | colspan="2" style="background:orange; color:black" | Orange |E |Electricity |- | colspan="2" style="background:yellow; color:black" | Yellow |G |Gas |- | style="background:blue; color:white" | Blue | style="background:blue; color:white" |Blue | rowspan="2" |W | rowspan="2" |Water |- | style="background:white; color:black" | White | style="background:blue; color:white" |Blue |- | style="background:green; color:white" | Green | style="background:purple; color:white" | Purple |T |Telecommunications, commonly used by Chorus for copper and fiber optic cables. |- | style="background:lightgrey; color:black" | Light Grey | style="background:red; color:white" | Red |SS |Waste Water / Sewer |- | style="background:darkgrey; color:black" | Dark Grey | style="background:pink; color:black" | Pink |SW |Storm Water / Drainage |- | style="background:red; color:white" | Red | | |Regional Utility Specific, commonly used by UFF for fiber optic cables. |- | style="background:purple; color:white" | Purple | | |Regional Utility Specific, known to be used by Telstra Saturn Cable Television |- | style="background:lightblue; color:black" | Light blue | | |Regional Utility Specific, known to be used by Telstra Clear |- | style="background:pink; color:black" | Pink | | |Regional Utility Specific |- | style="background:black; color:white" | Black | | |Most commonly used for non-potable water on farms however can be
