Issue new item (4)
I believe the answer is:
emit
'issue' is the definition.
(both can mean to give out or radiate)
'new item' is the wordplay.
'new' is an anagram indicator.
'item' is an anagram of 'EMIT'.
(Other definitions for emit that I've seen before include "Small turtle" , "Give out or put forth" , "Give off, gas say" , "Give off or discharge" , "Produce and discharge" .)
