A political commentator is warning the threat of a second election could deter people from casting a vote in the first place.
National has suggested a second election could be needed, if it fails to reach a governing arrangement with New Zealand First after Saturday's vote.
The New Zealand First leader Winston Peters says National is panicking because his party is rising in the polls.
Labour's Grant Robertson also thinks National is panicking about its potential coalition arrangements.
