The museum seems to still want to move away from its roots and origins, so it would appear. They've launched a blog and nowhere does it refer to those two words in the brackets. Their copyright notice says "Auckland Museum" but their website does mention those words on the home page. Small lettering. Top left, on the links bar. And here, on their war memorial page.
I'll be visiting the museum tomorrow, hopefully. I felt somewhat disheartened last time I saw it, this past summer. It seemed to have lost its cool vibe. I'm hoping some of that has started to return.
