Hamilton City Council has set aside $150,000 to fight SkyCity over its application to add 60 more pokie machines to the central city casino.
The council today voted 8-1 to put forward a submission to the Gambling Commission opposing SkyCity Hamilton's application.
The council will engage law firm Tompkins Wake and any other lawyers needed to put together and present the submission on the council's behalf.
The spend of up to $150,000 will be funded from an existing budget in the Mayor's Office.
Council chief executive Richard Briggs will also approach other parties to see if they would cover up to half the cost of the submission.
