The top 25 hotels raked in $253 million in poker machine profit - or player losses - during 2016-17 for an anticipated tax take of more than $100 million for the NSW government.

However, matching hotels and their owners with poker machine profit is difficult because the state government does not release individual figures.

Treasury documents tabled in the NSW Legislative Council following the state budget list poker machine profits for each pub, but do not name them.

Liquor and Gaming NSW information ranks NSW pubs by their pokie profit each quarter but does not specify the amount.

The Treasury documents show that in 2016-17 the top-ranked pub for poker machine profit made $13.9 million of which an estimated $6.1 million is payable in tax.

According to Liquor and Gaming NSW, the top-ranked hotel for pokie profit during the first six months of 2017 was the El Cortez Hotel at Canley Heights, owned by Redcape Hotel Group.

The El Cortez is in Fairfield local government area, ranked as Sydney's most disadvantaged.

Last month Fairfax Media revealed Fairfield council was calling on the NSW government to consider banning any more poker machines in the area amid a review of the rules for determining applications by pubs and clubs.

The Treasury data shows the second-highest earning NSW pub for pokie profits earned $13 million during 2016-17 at an average of $250,000 a week, with tax payable of $5.7 million.

The pub ranked by Liquor and Gaming NSW as second by pokie profit in the first half of 2017 is the Railway Hotel at Lidcombe, owned by the Malloy family.

The third-ranked hotel earned $12.9 million last financial year from its poker machines, with $5.7 million payable in tax.

The hotel ranked as the third-biggest earner of pokie profit during the first half of 2017 was the Markets Hotel at Flemington, owned by Garry Macdougall.

The remaining hotels in the top 10 earned poker machine profits of between $12.4 million and $10.2 million during 2016-17, with $33 million collectively payable in tax.

Liquor and Gaming data shows for the June quarter of 2017 they were the Eastwood Hotel (Redcape), Crossroads at Casula (Marlow Hotel Group), Meridian Hotel, Hurstville (Thomas Hotels), Cabramatta Inn (Redcape), Campsie Hotel (Thomas Hotels), Keighery Hotel, Auburn (Redcape) and the Crown Hotel, Revesby (Redcape).

NSW Greens MLC Justin Field said behind the profits there was "immeasurable harm caused to people, families and communities from poker machines".

He called for consideration of $1 bet limits and an acceleration in the overall reduction in the number of poker machines in NSW. Currently one out of every three machines traded must be forfeited to the state.

"The $252.97 million lost to addictive pokies in the top 25 hotels is no accident, these machines are designed for addiction and making profits from people and communities," Mr Field said.

"The vested interests in the hotel industry continue to push to wind back regulations on gambling. It's long past time government reined them in and put people before pokies profits."

The NSW division of the Australian Hotels Association declined to comment.

NSW Racing Minister Paul Toole said the government "is currently considering reforms to the Local Impact Assessment scheme, transparency of gaming machine information and responsible gaming initiatives."

"The government will be considering all the evidence during this process, not just numbers cherry-picked by the Greens," he said.

"The Greens are opposed to all forms of gambling for ideological reasons, and they should just come clean and admit that."
