Prime Minister John Key flew out of the US after an Oval Office visit yesterday, saying: "It's hard to see the relationship getting much better."
His personal friendship with President Barack Obama, forged over Trans-Pacific Partnership (TPP) talks and the Honolulu golf course, has had pay-offs in the political relationship.
The golfing connection was evident in Obama's gift to Key, a putter engraved with his signature and the presidential seal and Key's initials, JPK, for John Phillip Key, along with some presidential golf balls.
Key left a set of black merino sweaters by Untouched World for Obama and his family.
