Pauline Hanson has waded into the growing controversy over the Baird government's part privatisation of power company Ausgrid​, telling federal Treasurer Scott Morrison: "Don't sell our assets".

The One Nation senator has posted a video on her Facebook page, noting that Mr Morrison has "on his desk" decisions about three potential asset sales: Ausgrid, gas company Alinta and health company GenesisCare.

The sales are being scrutinised by the Foreign Investment Review Board, which will advise Mr Morrison on federal government approval.

The NSW government is leasing 50.4 per cent of Ausgrid on a 99-year lease in a deal expected to be worth more than $10 billion.
