Poll results are listed in the table below in reverse chronological order, showing the most recent first, and using the date of publication, as opposed to the date the survey's fieldwork was done, which can be seen in the second table. The highest percentage figure in each polling survey is displayed in bold, and the background shaded in the leading party's color. In the instance that there is a tie, then no figure is shaded. The lead column on the right shows the percentage-point difference between the two parties with the highest figures. When a specific poll does not show a data figure for a party, the party's cell corresponding to that poll is shown empty. The client can be seen in the second table.

(*) It is commonly assumed on the basis of results from previous elections and past experience that HDZ will win a majority (if not all) of the 3 seats allocated to the XI electoral district made up of Croatian citizens living abroad. Should this be the case HDZ would have a total of 58 seats, with 56 being considered safe seats and raising its possible seat range to 56-63.

(**) The 11 remaining seats are allocated in the XI (3) and XII (8) electoral districts. The XI electoral districts encompasses all Croatian citizens living abroad. The XII electoral district encompasses members of 22 recognized national minorities who elected representatives in a single district with the votes being subsequently allocated to candidates running for every minority's individual seat. The Serb minority elects 3 members, while 1 seat each is allocated to the Italian, Hungarian, Czech/Slovak, Albanian/Bosniak/Macedonian/Montenegrin/Slovene and Austrian/Bulgarian/German/Jewish/Polish/Roma/Romanian/Rusyn/Russian/Turkish /Ukrainian/Vlach minorities.
