Boot produced in New Zealand city (10)
I believe the answer is:
wellington
I believe this is a triple definition!
'boot' is the first definition.
(Wellington boots are a type of boot)
'produced' acts as a link.
'in new zealand' is the second definition.
('Wellington' is part of 'new zealand')
'city' is the third definition.
(Wellington is an example)
(Other definitions for wellington that I've seen before include "beef-dish?" , "Waterproof boot" , "The Iron Duke" , "Victor at Waterloo" , "NZ capital" .)
