The NSW government has reversed its position on selling surplus land acquired as part of the WestConnex roads project, promising no decision would be made until its proposed public spaces minister was appointed.

Labor accused the government of hypocrisy over the intended sale of about 4000 square metres of land at Homebush, acquired as part of the $16.8 billion road project but not needed after construction.

Although local councillors had been informed of an intention to sell, WestConnex Minister Stuart Ayres said in a statement on Sunday the land was "not being considered for sale".

The reversal came after the Herald contacted the Minister's office with questions about how the proposed sell-off would fit with the government's renewed commitment to open public space.
