Wellington - New Zealand's election on November 8 pits Helen Clark, a parliamentary veteran and one of the astutest politicians the country has seen, against John Key, a political learner who would be the most inexperienced prime minister elected in more than a century if he wins.
Clark, 58, has been a Labour member of parliament since 1981 and, not satisfied with making history as the only leader of the party to win three consecutive elections, is bent on winning a fourth for another three years in power.
Key, 47, did not enter parliament - where he is the richest member, having made a fortune as a foreign currency dealer overseas - until 2002, and he has led the main opposition conservative National Party less than two years.
