According to what i found on another board (not posting it since it would be kinda advertising)
TAR filming was spotted at the Auckland Airport on 2/21/04 at 11 AM.
First team was 11 AM
6th/last team was 1:30 PM
There were NO male/male teams
It was an arrival, therefore some tasks in New Zealand
This does make the Phillipines spolier possibly true (the spolier said they were visiting on Feb 24th).
And thats it...been proven true by many on the board I found it on.
