Seems Blair's being a little cheeky; frame grab was from Chathams. Seems to me hapuku are primarily a deep water species. Apply any more than mild pressure to the deep reefs and the shallow 'puks will move out to fill the vacated habitat. I wonder if there is some other variable that has kept the 'puks in shallow at the Chathams when they left seemingly identical mainland ecosystems decades ago? I suspect not, and if so, inexorably the hapuku will vacate the shallows at the chathams too, shifting the baseline further still
