The National Party has dropped below 25 percent in the latest RNZ-Reid Research poll, while Opportunity has reached a new high and could decide the next government.
National has dismissed the result as "out of step" with other polls, just nine days before voting closes.
Christopher Luxon's party is on 24.8 percent, down 1.1 percentage points since the last RNZ poll three weeks ago. That puts National below its disastrous 2020 election showing, though still above its historic low in 2002.
Labour remains the most popular party on 30.6 percent, down 0.2 points, while Opportunity records the biggest gain, rising 1.7 points to 7.2 percent.
