Helen Clark will be laying low in New York this week preparing for her crucial appearance at the United Nations General Assembly early Friday, NZ time, about her bid to run the show.
Each of the candidates will get an individual two-hour session with as many representatives of the 193 members who want to turn up.
Each is also asked to submit a written statement of up to 2000 words.
Soon after the former Prime Minister declared her candidacy on Tuesday she took off for a scheduled conference in Cairo as head of the UN Development Programme and arrived back in New York on Friday. "It was a major conference between the League of Arab states UNDP and the Government of Egypt on the sustainable development goals and I didn't feel I could withdraw from it."
She said she did not use the conference to campaign.
