The polling period was August 1-11 and has a margin of error of 3.1%.
Labour leader Chris Hipkins was up one point in the preferred Prime Minister stakes to 23%, overtaking Luxon who was steady on 22%.
The latest Herald-Motu Research Poll of Polls, which does not include this poll, suggested the coalition would narrowly be able to form a Government.
The model showed National polling 30.2%, one point ahead of Labour on 29.2%. NZ First had 12.4%, the Greens 10.9%, Act was estimated to be on 7.1%, and Opportunity was close behind on 6.9%.
