Noboa, 35, would win 41.5% of total votes, including blank and void ballots, while Gonzalez, who led the first round of voting, would garner 36.4%, according to polling firm Comunicaliza.
The survey, conducted this week, included 5,265 people and had a margin of error of 1.35%.
Some 17% of the 3,000 people polled are still undecided, while 5.3% would hand in protest ballots, Negocios & Estrategias said.
This contest was called by current President Guillermo Lasso after he dissolved the legislature to avoid impeachment.
