Campbell Newman has resigned as Premier of Queensland following the state election 10 days ago.

Mr Newman visited Governor Paul de Jersey and had a 40-minute meeting to tender his resignation, pending the appointment of a new premier.

"In accordance with my constitutional duty, I have agreed it is my obligation to remain in office as caretaker Premier until that time," Mr Newman said in a statement.

"It is a duty I take seriously and one I will continue to undertake to the best of my ability."

Governor de Jersey said he would commission a new Premier following the poll declaration.

The cut off for postal votes ends at 6:00pm today but final declarations could take days.

By 1:30pm Tuesday, 25 seats had been declared in the 89-seat Parliament.

Labor and the LNP have been tussling over who will claim power after a clear majority did not emerge in the state election on January 31.

They entered negotiations with independent Peter Wellington and two Katter's Australian Party (KAP) MPs, with Labor succeeding in securing Mr Wellington's support.

About 4pm, Labor leader Annastacia Palaszczuk visited the Governor for a "courtesy call".

"Seats are yet to be declared & visit to @QldGovernor is a courtesy call to discuss current issues pertaining to the Jan 31 election," Ms Palaszczuk tweeted.

The visit to Government House lasted about 30 minutes.

Ms Palaszczuk did not address the waiting media as she left.

The LNP looks likely to win 42 seats, and would need to secure Ferny Grove in a by-election and the support of the two KAP MPs to claim power.

It is unclear at this stage whether a by-election will be called in Ferny Grove after a candidate was disqualified.

Palmer United Party candidate for Ferny Grove Mark Taverner, who had received 1,000 votes, was found to be an undischarged bankrupt and therefore ineligible to run in the seat.

The Electoral Commission of Queensland announced on Sunday it would refer the northern Brisbane seat to the Court of Disputed Returns after the seat was declared.

The court will then determine whether to order a by-election.
