Company has time to rebuild NYC (6)
I believe the answer is:
agency
'company' is the definition.
(thesaurus)
'time to rebuild nyc' is the wordplay.
'time' becomes 'age' (an age is a period of time).
'to rebuild' is an anagram indicator (I've seen this in other clues).
'nyc' is an anagram of 'ncy'.
'age'+'ncy'='AGENCY'
'has' is the link.
(Other definitions for agency that I've seen before include "Business serving other businesses" , "Business that acts for another business" , "Type of business" , "Business that represents actors etc." , "Travel ..., advertising..., employment" .)
