So much for Oravida, Judith Collins, Maurice Williamson. National's troubles of the past two months have evaporated in two separate public opinion polls taken since the Budget. Colmar Brunton, for TVNZ, and Reid Research for TV3, both find more than half of their sample intending to vote National. This must be devastating for Labour, whose sustained barrage on Ms Collins in Parliament over the past two months does not appear to have moved any votes.
The latest results are strikingly similar to those in a Herald-DigiPoll survey in March, shortly after Labour's barrage began. Then, as now, National had 50-51 per cent and Labour 29-30 per cent. National's numbers were 4 per cent lower in the television polls last month, suggesting the May 15 Budget has given it a boost.
Extending paid parental leave and making medical treatment free for all children may have paid a political dividend. The public may also be rewarding National for its curb on public spending that has all but cleared the recession deficit and enabled the Government to project a better-than-expected surplus.
Much as Labour and the Greens must hope the latest polls are no more than a post-Budget bounce, they do not look like it. They are consistent with polls over the past three years, suggesting the April drop was the temporary flux. If conflict-of-interest questions over Ms Collins' Oravida dinner in China had any impact, they have not changed votes.
Four months out from the election, Labour is the party in trouble. It ought to be polling well above 30 per cent by this stage to have much hope of success in September. If its result is not 10 or more points higher at the election, it must be doubted it could lead a credible government.
