A woman has died after she was repeatedly stabbed in front of her four children at a picnic area in a national park in New Zealand.
Police say a man drove into the picnic area, got out of his car and immediately attacked 34-year-old Tracey Patmore.
The man then grabbed the youngest child and drove off, prompting a police chase involving an armed police unit which caught him 30 minutes later.
The child was reunited with his family but his mother died at the scene despite the efforts of bystanders to save her.
A 31-year-old man is being questioned by police.
