While scanning the net, I found this over at Tolkien-Movies. The article appeared in the Southalnd Times, and covers the shooting schedule and it starting again after the Christmas Break.

The Lord of the Rings director Peter Jackson and entourage assemble gear at Queenstown Airport yesterday for a flight to Wellington.
Jackson joins cast and crew returning to their homes for Christmas after filming finished in the resort on Thursday.
Pre-production work resumes in Wellington on January 3 and filming would start there again on January 17.
Filming is not scheduled to resume in Queenstown again until the middle of next year.
