It's a serious question and one for DT!
Apparently, NZ PM has had the most meetings and games of Golf with Obama than ANY other country on the planet.
Apparently, the pair are "best friends" on a personal level and have regular games of Golf in Hawaii, California and even NZ.
They have met each other many times just for Golf alone mate. The relationship between Obama and NZ PM is apparently something a lot more than any other country.
