Coalition regain voters in latest Newspoll

Voter support for the government has resurged with the latest Newspoll showing a significant rise for the coalition - up three percentage points in three weeks.

As parliament returns this week for a crucial fortnight before the budget, the coalition is at 48 per cent to Labor's 52.

That's compared to February polling which had Labor at 55 to the coalition's 45 on a two-party preferred basis.

The coalition's primary vote has grown from 34 to 37 per cent while Labor's has dropped 37 to 35 per cent.

The poll was taken after Prime Minister Malcolm Turnbull's announcement of a $2 billion upgrade of the Snowy Hydro scheme.
