Geordie staff maintaining enthusiasm for country (3,7)
I believe the answer is:
new zealand
'country' is the definition.
(New Zealand is an example)
'geordie staff maintaining enthusiasm' is the wordplay.
'geordie' becomes 'ne' (I've seen this in other clues).
'staff' becomes 'wand' (wand is a kind of staff**).
'maintaining' is an insertion indicator.
'enthusiasm' becomes 'zeal' (zeal is a kind of enthusiasm).
'wand' placed around 'zeal' is 'wzealand'.
'ne'+'wzealand'='NEW ZEALAND'
'for' is the link.
(Other definitions for new zealand that I've seen before include "Zelanian things originate here" , "Commonwealth country" , "[TEST TEAM]" , "where 28/25 [PINOT NOIR] is produced" , "Antipodean country" .)
