Protagonist hides somewhere in New Zealand (5)
I believe the answer is:
otago
'somewhere in new zealand' is the definition.
(I know that Otago is in New Zealand)
'protagonist hides' is the wordplay.
'hides' indicates a hidden word.
'OTAGO' can be found hidden inside 'protagonist'.
(Other definitions for otago that I've seen before include "Region of New Zealand around Dunedin" , "Antipodean region" , "Part of South Island" , "part of New Zealand" , "Council region of New Zealand" .)
