UPDATED 4.45PM

Deteriorating weather conditions are postponing police efforts to retrieve a body found on Fox Glacier.

A tramper found the body - which Police say has been there for some time - at around 10.30am.

A Police spokesman said conditions are too unsafe for planes to fly to the glacier, and it could be days before the weather improves.

He said they will require a post-mortem to identify the body, and will then alert the next of kin.
