Te Papa has made $750,000 since it started charging international visitors an admission fee two months ago.
The change came in during September to help fund rising energy, insurance, and staffing costs at the museum.
Te Papa head of marketing and communications Kate Camp says New Zealand's tourism industry is a rich area with plenty of room for 'once-in-a-lifetime' experiences.
"You're not here for a cheap and cheerful holiday, for most of our visitors."
