After holding back on the jokes while in China, it didn't take Prime Minister John Key long to crack once he was back among New Zealanders.
Mr Key spent a day in Hong Kong meeting its chief executive and attending tourism promotion events.
Speaking to expat Kiwis at the plush Hong Kong Country Club, Mr Key reprised them of his visit to China, including the deal to allow direct currency conversion between the NZ dollar and China renminbi.
"You can now convert New Zealand dollars into renminbi, if you are of such a mind to do so. So, life after politics, I might go back to the foreign exchange markets and smack around the renminbi. Maybe not."
Mr Key also spoke about the Hong Kong Sevens, due to take place next weekend. He said the only time he had been was "a very messy affair, I have to say."
