Fabric Greek character finally bought in New Zealand (6)
I believe the answer is:
chintz
'fabric' is the definition.
(I know that chintz is a type of fabric)
'greek character finally bought in new zealand' is the wordplay.
'greek character' becomes 'chi' (letter from the Greek alphabet).
'finally' suggests the final letters.
'in' is an insertion indicator.
'new zealand' becomes 'nz' (abbreviation).
The last letter of 'bought' is 't'.
't' placed inside 'nz' is 'ntz'.
'chi'+'ntz'='CHINTZ'
(Other definitions for chintz that I've seen before include "Shiny cotton fabric used for furnishings" , "Glazed cotton cloth with printed pattern" , "'Cotton fabric, often used for curtains or upholstery (6)'" , "Floral cotton cloth" , "Printed cotton fabric for curtains or upholstery" .)
