So this is what you get:
A man has discharged a firearm in the Ashburton Work and Income new Zealand (WINZ) office this morning.
The incident happened at the WINZ office on the corner of Cass and Moore streets.
Police said in a statement that the man left the scene on a push bike and should not be approached.
Locals were advised to take precautions and stay indoors.
Anyone with information should contact Christchurch police on 03 363 7300, or could provide information anonymously by calling Crimestoppers on 0800 555 111.
