Aucklanders reportedly flocked to open homes on Sunday, surer of their spending power post-election.
Industry bosses are expecting sales to recover now the election is over and spring is on the way.
Peter Thompson, Barfoot & Thompson managing director, said such a strong election result had resulted in agents already seeing more open home attendance, as confidence returned.

"People have been holding off putting their properties on the market. Already, yesterday, more people were at open homes," said Thompson.
Barfoot figures showed that sales volumes had slumped before the election and Harcourts also cited the election for fewer sales.
"Last week, we had 220 sales compared to the same week last year when there were 340," he said.
Spring was also a traditionally strong time for property trading, he said.
Helen O'Sullivan, REINZ chief executive, said more house buyers and sellers would move in the next few months, because volumes had slumped just before the election.
Spring would just push the market further, she predicted.
"We've seen the tightness of the stock and volumes down about 20 per cent year-on-year and last month our listing figures were very low. We'd like to see the listing figures start to improve. There's new stock coming to the market in Auckland and a lot of building work going on.
"The rate of price growth has levelled out and I think we would probably expect to see that continue. Auckland and Christchurch are the two places with significant price increases and that's driving the national figures and those two areas are the most supply-constrained.
"Prices will continue to increase but at a lot lower rate than at this time last year. I don't see another burst like we have had. The market is still volume constrained. We'll be looking for an indication from the Reserve Bank of the end to the LVR regime," O'Sullivan said. "They always said they were temporary, but what's the flat where the restrictions are on their way to being removed."
National's policy on more first home buyer assistance would see more younger people being able to afford houses, she said.
