Foreign Minister Murray McCully believes former Prime Minister Helen Clark had the best start possible in the first phase of her bid to become the next Secretary General of the United Nations.
It was such a strong start that he does not think the late entry of former Australian Prime Minister Kevin Rudd would damage Clark's chances very much.
"Obviously it might send a mixed signal to some countries about our part of the world but I think Helen has established a firm profile of her own and if Kevin Rudd does come in, I don't think it is going to change her fortunes greatly," Mr McCully said in an interview from Europe.
"The fact that someone from our part of the world is regarded as a front-runner is I think an indication that it is going as well as it could possibly go at this stage."
Mr McCully met up with Helen Clark in New York last week when he attended a Security Council debate on the Middle East, following a session the previous week in which all nine candidates had an individual session with the General Assembly.
"You'd have to say that Clark has had the best launch and had one of the most impressive performances before the General Assembly body," he said. "The general comment from people in New York was that she had been one of the best two."
The other was former Portuguese Prime Minister Antonio Guterres.
It is clear, however, that many countries are reserving their judgments for the time being.
Of the nine candidates in the contest, seven are from Eastern European countries. There has never been an Eastern European Secretary-General, but no clear consensus has emerged around one of them.

After New York Mr McCully went on to London to meet Foreign Secretary Philip Hammond and to Germany to meet Foreign Minister Frank-Walter Steinmeier. Prime Minister John Key has been actively lobbying too and on his visit to China last week said he would be "stunned" if China vetoed Clark.
Mr McCully said there was "an acute level of sensitivity" to the interests of Eastern Europe. "For that reason countries [will not be rushing in with early commitments]."
Phase two of Helen Clark's campaign was a first round of visits to capitals of Security Council members, who will eventually recommend a candidate to the General Assembly, and other influential countries.
There is no deadline other than the appointment needing to be made before the end of the year when Ban Ki-moon's term ends.
Straw votes at the Security Council in past selections have involved member countries giving one of three ratings to candidates - encourage, discourage or no opinion - until a consensus emerges.
