Restrict OSM address auto complete to one country

Hi there.

Just wondering how to restrict OSM address auto complete to one country/ default country?

At present when say using ‘add listing’, when you start typing an address it shows random addresses from all around the world? How can i restrict this to just my country (New Zealand)

I have tried adding the custom script into the footer as per a previous similar question on the forum but its not working …assume its for Google maps only ?

<script>
jQuery(function() {
if(typeof autocomplete != “undefined”){
autocomplete.setComponentRestrictions({‘country’: ‘uk’});
}
});
</script>

Thanks and look forward to hearing from you.
