I'm not sure of they were able or not to build buses for the home market but I cant think of any Metsec bodied buses bought new by UK operators - at least not deckers.

I'm pretty sure that some Citybus vehicles were put together by Caetano rather than being built up in the UK or Hong Kong.
Here is one of the Cityflyer buses which IMO were some of the nicest buses in Hong Kong at the time. A number were bought by both KMB and NWFB to:
