Support for Labour has taken a slide while National has picked up support in the wake of this year's Budget, according to a new poll.
The Fairfax-Ipsos poll, published in Fairfax newspapers today, shows support for Labour fell by 4.4 percentage points to 31.9 per cent.
National picked up slightly more support than Labour lost, with a 4.5-point lift putting National's support on 49.4 per cent.
The poll, taken in the week following the Budget, puts National in a much stronger position than the February poll, when left and right were almost evenly matched.
Based on the poll results, National would pick up 63 seats in Parliament if an election was held today - enough to govern without support partners in a 124-seat Parliament.
