Tyneside fellow finally up to date (3)
I believe the answer is:
new
'up to date' is the definition.
'tyneside fellow finally' is the wordplay.
'tyneside' becomes 'ne' (region in North East of England).
'finally' indicates one should take the final letters.
The last letter of 'fellow' is 'w'.
'ne'+'w'='NEW'
(Other definitions for new that I've seen before include "and 28 and 29: The 365th day" , "Unconventional" , "Recently made, etc" , "Fresh, recent" , "Unused or novel" .)
