'Wound-up' pig bites woman on leg

A woman was airlifted to Palmerston North Hospital on Saturday after being bitten on a leg by a "wound-up" pig.

The Square Trust rescue helicopter was called to a farm near Eketahuna late in the afternoon after the woman, 41, was bitten by a boar while shifting stock.

A spokesman said the boar was "wound-up" because a sow was in season.
