Mr Peters criticised the Government's contention that to not sell the Crafar farms to a Chinese business would be prejudicial.
He said this was a poor argument given the Chinese government had forbidden sales of its own land to foreigners.
"It is a lie because it means that the Chinese can buy our land but we cannot buy theirs. There is no thought of doing the right thing by our people."
The NZ First leader also criticised the Government's deal with SkyCity, which could allow the casino to install more pokies, and National's selling of state houses.
Mr Peters reiterated NZ First's campaign for elderly people to get a 10 per cent discount on their power bill.
When this proposal was raised last week, National argued a discount was not financially sustainable and said power prices had risen steeply when Mr Peters was part of a coalition government.
NZ First was also proposing cheaper doctor's visits for the elderly. Under Mr Peters' proposal, the elderly would receive their first doctor's consultation free and would pay $10 a visit for their first five consultations.
Mr Peters estimated the annual cost of the plan was $90 million, but believed it would reduce expensive hospital visits.
