UPDATE 8.38AM:Â Police are working to identify a body found on Sumner Beach.
Emergency services were called by a jogger around 4.30am
They say a post-mortem will be carried out.
The discovery comes after police called off their search for Christchurch schoolboy Jack Sutton who disappeared while swimming off Scarborough Beach last Monday.
Sumner lifeboat coxswain Blair Quane has thanked the local community for tents, portaloos, campervans and heaters as the 14-year-old's family kept a vigil at the beach.
"Without that support, the family certainly couldn't have survived so well down on site the whole time."
More than 93 boats with voluntary crew have searched the Canterbury coast over the last few days.Â
