Mr Chaney expected the cinemas to be "fairly busy" for the first few weeks while the big Twilight fans got in to see the movie.
"There are some pretty hard-core fans out there. They are always dressed up and get right into it, so it's a bit of fun," he said.
Popular preconceptions view Twi-hards - diehard Twilight fans - as mostly young teenage girls with a big crush on the movie's leading men.
Not so in Tauranga.
Welcome Bay woman Kristy Smith admitted she was a major Twi-hard and "no, I'm not a teenager either".
Mrs Smith is a 32-year-old wife and mother of two boys, and she can't get enough of Edward. She said she will be going to watch Breaking Dawn as soon as she can get a ticket.
"I saw the first movie and then right when New Moon was coming out I went and got the books... I've seen all of the movies at least a dozen times each, which is completely ridiculous and embarrassing. With Eclipse I saw it three times at the theatre."
Mrs Smith said she had fallen in love with the story's concept of old-fashioned romance, albeit with a vampire/werewolf twist.
Mrs Smith and a group of friends traditionally gathered before the release of a new Twilight movie to have "Twilight parties" and watch previous movies in the series before going to see the latest.
"But I'm the biggest Twi-hard of the group," Mrs Smith said.
Tauranga woman Karolyn Timarkos has already got her ticket to the upcoming midnight session.
"I went to the last one thinking 'how embarrassing, it'll be me and a theatre full of 13-year-old girls'. How wrong."
Ms Timarkos said she was one of many women aged in their 40s who packed out the cinema.
"I even caught up with a chick I went to school with I hadn't seen for 20-something years, who drove up from Taupo with a mate because our cinema is better than theirs."
