Newshub's imminent closure has put the size of our population in the spotlight. 

Advertising agency owner Vaughan Davis told Mike Hosking that New Zealand is like the Chatham Islands of the world.  

He said that maybe we're just too small a country for two TV networks. 

Davis said we try to have the big country stuff but it's just five million people on an island, far away from everywhere. 

Up to 300 jobs are expected to be lost by the end of June.
