I believe the answer is:
errand
'gofer's task' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for errand that I've seen before include "Short journey done for others" , "Short trip for a message" , "Job usually involving a short trip" , "purposeful journey" , "Trip for small task" .)
