The NSW Government's $1 billion stadiums plan could be in line for a cash injection if the Land and Property Information service is privatised.

In September, Treasurer Gladys Berejiklian announced a study to investigate future options for the LPI including possible private investment.

The service looks after property information, valuations, surveying and mapping of land in NSW.

The Government has confirmed the study was still underway but if the privatisation went ahead some of the funds would be used for stadiums package.

It has already set aside $600 million for the package as part of Rebuilding NSW.

Premier Mike Baird has touted it as the biggest investment in sporting and major event infrastructure in the state since the 2000 Olympics.

It includes a new 30,000 seat stadium at Parramatta, in Sydney's west, and a new rectangular stadium at Moore Park in Sydney's east to seat up to 55,000 people.

The Government is also looking to acquire the lease of the Olympic Stadium to redevelop it.

A spokesman for the Treasurer said no private operator had been earmarked.
