Details of the next float of state-owned assets will be announced in the Budget on 16 May.
Finance Minister Bill English said on Thursday that will provide more opportunities for more so-called mum and dad investors.
The Government is under fire from the Opposition over the partial sale of Mighty River Power.
It is blaming the Labour and Green parties' energy policy for the fact that less than a third of New Zealanders followed through on their pre-registration intentions to buy shares.
However, Mr English said the Government is expecting "a cleaner run" when other state assets are floated.
Mr English admitted the asset sale programme has probably cost about $100 million so far.
