Figures from the lead-up to the 2011 general election, which was held on November 26, show the agency's Auckland housing sales remained relatively steady - with 727 house sales recorded for October that year, down slightly from 738 in September.
New listings with the agency from the period actually increased, up 4 per cent from 1263 in September to 1314 in October 2011.
Bayleys, which released a 3-month analysis of the Auckland residential market recently, said a drop in sales around the general election was expected.
"Annually, residential sales volumes drop throughout the winter period," managing director Mike Bayley said.
"Compounding that, every three years the pace of sales also decreases in the 12 weeks leading up to a general election.
"This year, the market has also been restrained by two fiscal factors - rising mortgage interest rates for the first time in some four years, and the effect of the loan-to-value lending criteria imposed by the banks."
Figures from the Real Estate Institute of New Zealand - which records all sales - were not yet available for last month's housing deals in Auckland.
However, institute figures from 2011 show the number of sales in Auckland dropped 4.7 per cent in the two months before the November general election - from 1922 in September to 1832 in October.
Nationally, the number of house sales dropped 4.4 per cent between September and October that year.
