They've recently captured several giant squid in New Zealand waters, so they know approximately where to look. No, these squid were brought up by fishermen who were trawling for a fish called the orange roughie. This is over a fairly shallow area called the Chatham Rise, which is essentially an undersea plateau. Not really, because we've never actually observed them. Hopefully, part of a long form with an extremely large eye.
Giant squid have the largest eyes of any living creature in the world, the size of a dinner plate.
These are extremely complex and sophisticated eyes, too. The ocean is more or less divided into layers. Some creatures live near the surface, some live in midwater, and some live at great depths. There are some that migrate toward the surface at night. I can't tell you what exactly can be found in this particular area, but since it's fairly shallow, it should be crowded.
