Now he's on terra firma, living next door to the American Vice President in DC's diplomatic dress circle, Groser is bringing his well-honed art of winning friends and putting them under the influence of our blip on the radar screen that we proudly call home.
He threw a Donald Trump inauguration party that cost us more than $80K, or just over $250 a head for those who attended. It's been called a get together for D-list celebs by the penny pinching Taxpayers' Union.
But in reality there were Trump big hitters, like his Chief Strategist (yes he actually has one) Steve Bannon and our very own Kiwi collaborator Chris Liddell, who's very much on the Trump advisory team, along with senior politicians and a sprinkling of generals and business big wigs.
The official Wellington line is that it's the embassy's job to pursue New Zealand interests with the United States.
It's ironic that Tim Groser, the man who for several years pursued our main interest, getting a backdoor trade agreement with Uncle Sam through the Trans Pacific Partnership, was the party host.
Groser reflected the view of many when he justified the party saying very few people in the United States, let alone the diplomatic community, have any idea of who the administration are or who is deeply influential, which when it comes to Trump would seem to be something of an oxymoron.
