From a post by Steve Hathaway (http://www.stevehathaway.com) on another site I frequent ...
"Here's a press release about a filming project I've been involved with this year. I'm now on call to film Orca for the next 5 months - If any of you see Orca out there can you please call 0800 SEEORCA straight away so we can get out there and hopefully capture some unbelievable footage.
It will be screened on the TV series coming out next year called "My Big Blue Backyard"- 6x1 hour underwater episodes that we've been shooting around NZ. It will be very cool!!
If you see Orca give them a call. It sounds like they will be filming in northern NZ but any other info on locations, photos for ID etc. would be useful.
