Czech tourist Pavlina Pizova has described the death of her partner and the month she spent in the New Zealand wilderness after the couple set out on an ill-fated hike.

Pizova was rescued Wednesday from a park warden's hut on the snowed-in Routeburn Track near Queenstown, and Ondrej Petr's body was recovered Friday.

She says she couldn't free her partner after he slipped down an icy bank and became wedged between rocks and branches. After he died, she stayed with him through the freezing night.

Pizova broke down in tears as she read aloud her account in halting English. Czech Consul Vladka Kennett provided more details.

She said she and Petr made mistakes as they set out on their hike July 26 and the extreme weather conditions they encountered.
