How to exclude visits from country Google domain

I want to exclude visits from a country specific version of Google

Is there a way to easily set up a custom report to exclude any visits from say www.google.com.mx and any visitors from that country?

Am I missing something here? It doesn't seem to be working.

Filter Type: Custom >> Exclude
Filter Field: Visitor Country
Filter Pattern: New Zealand
