Vojko Obersnel, the 14th[1] and incumbent mayor who has been in office since 2000, ran for a sixth consecutive four-year term, finishing in 1st place with 41,00% of the vote in the first round.

However, as no candidate won an absolute majority of the vote in the first round, a second round of elections was held on 4 June 2017 between the two highest-ranked candidates in terms of popular vote: Vojko Obersnel of the Social Democratic Party of Croatia, and independent Hrvoje Burić .

Obersenel defeated Burić by a wide margin in the run-off, taking 55,6% of the vote to Borić's 42,7%.

They also expressed concerns about the other candidate Hrvoje Burić who, as a former city councilor, has long represented more than crude rhetoric with extreme conservative politics.
