John Key is drawing more female voters for National than Don Brash ever did - but Helen Clark's Labour is still the women's party.
Analysis of four DigiPolls in 2005 and six this year suggests that, while women have been flocking to the Key National party in greaternumbers than men, they have not been doing so in dramatically greater numbers.
National has increased its DigiPoll ratio of women by 2 per cent - from 45 per cent in 2005 to 47 per cent this year. Its male ratio has correspondingly fallen from 55 per cent to 53 per cent.
The reverse is the attraction to women of Clark's Labour: 55.5 per cent of its support this year against 56.5 per cent in 2005, with a converse rise in the male ratio to 44 per cent.
The biggest DigiPoll shift has been in New Zealand First's support. It is more a male party this year (54 per cent) and its share of women has dropped 3 per cent. But readings for the small parties should be treated with caution: subsamples are small and subject to error.
* The four 2005 DigiPolls were in August and September. The six this year are monthly from April. According to Statistics New Zealand, the over-18 population divided roughly 51.8:48.2 in 2007. DigiPolls do not exactly replicate that.
