Te Papa has reopened after closing for a few days after the 7.5 magnitude earthquake that struck Monday morning.

The Wellington museum was closed on Monday and Tuesday while the building and collections were assessed. The building was cleared by engineers as structurally safe but a small number of collection items were damaged in the quake.

The museum is back to its normal opening hours of 10am-6pm, seven days a week.

Chief executive Rick Ellis was pleased to be able to welcome visitors back to the museum.

"All Te Papa's exhibitions and facilities are open, with just a few spots where we are still tidying up.

"Our team are all safe and well, and the collections have come through brilliantly."

Te Papa's research facility in Tory St was also unharmed, and has been assessed as structurally sound.

Ellis said seismic restraining work at the museum in recent years had protected the collections.

"We are very grateful for our good fortune, and sending aroha to everyone who has been affected out there.

"Our message to everyone is haere mai and welcome back to Te Papa."
