John Key will have to pick his way through a diplomatic minefield when he hosts Japan PM Shinzo Abe in Auckland on Monday during his first formal visit to New Zealand.
Abe's charisma will also be on show when he visits Christchurch to pay tribute to the 28 Japanese citizens who lost their lives in the February 2011 earthquake. There is a strong relationship building element to the visit by the politician whose signature economic reforms - particularly the "third arrow" or growth strategy - have been dubbed Abenomics.
But from the NZ Prime Minister's perspective there is business to be done. When the Abe visit was first scheduled it was portrayed as an opportunity for Key to emphasise the "Pathway Forward" for the conclusion of the controversial Trans Pacific Partnership free-trade pact - known as TPP - which has been agreed between Abe and Barack Obama earlier this year.
But the Abe Cabinet's decision to end the post-World War II ban on Japanese troops fighting overseas means Monday's visit will take on an even stronger geo-strategic focus. Particularly as China is opposed to Japan asserting its military "rights" to protect its own overseas interests.
These issues are fundamentally of much more importance to New Zealand than which mid-level foreign affairs protocol officials failed to convey a direct message that claiming diplomatic privileges for the Malaysian diplomat Muhammad Rizalman bin Ismail over the alleged sexual assault of a young woman was not a goer.
