National falls behind, left bloc can form government in latest poll

National has dipped into the twenties, while New Zealand First has hit double-digits, in a new poll. The latest Taxpayers Union-Curia poll has National down 3.5 percentage points to 29.6%. Labour has also taken a bit of a hit- but the left bloc would have 21 seats in total - which would be enough to form a government. Political reporter Giles Dexter spoke to Lisa Owen.
