Rotorua Museum to remain closed following detailed assessment
A comprehensive assessment of Rotorua Museum has shown it falls well below earthquake safety standards and will need to remain closed for the foreseeable future.
The good news is that it can be fixed. How that happens, how long it will take and how much it will cost now needs to be determined.
Rotorua Mayor Steve Chadwick says while the closure of the much-loved museum building is devastating for the community and for Rotorua Lakes Council, public safety is the priority.
“The wait for the results of the detailed assessment has been frustrating for us all but it has been necessary to ensure we have a clear picture of what we’re faced with. We will now need to consider the options for both the building and the future of our museum services and make a decision about how to proceed.
“It is sad to see her closed but our iconic museum and Government Gardens remain popular and our wonderful museum staff and volunteers continue to provide events, tours and education programmes,” the mayor says.
“They’re an incredibly passionate and positive bunch and we’re all very proud of how they have embraced the concept of a museum ‘outside the walls’.”
The result of the detailed seismic assessment – which included invasive testing – assessed most of the building at 15% of the National Building Standard (33% or below is earthquake prone). That means the building will need to undergo substantial work before it could open to the public again.
Assessment of the building by engineers has shown repairs are needed to the roof, there is substantial timber and joint deterioration and there are internal pumice walls which have no steel reinforcement and would be seriously compromised by certain movement.

We now have a clear understanding of what state the building is in,” says Rotorua Lakes Council Chief Financial Officer Thomas Collé, who manages Council’s property team. “That means we can start working with our engineers, architects and Heritage New Zealand to understand what our options are, consider the work involved and the estimated cost of each option to bring back to Council for its consideration and a decision. That will take several months.
“Funding options will need to be explored too but again, it’s too early to guess how much might be needed,” Mr Collé says.
In the meantime, museum staff will continue to run events, Council’s Arts and Culture Director Stewart Brown, says.
“It’s too early to speculate about what the operational or business side of things will look like in the future,” he says. “We will be working through that during the coming months.”
“Taonga in all but the Te Arawa collection area – excluding some of the marble Summers sculptures which we’ll have removed soon – were moved out and into storage some time ago. The majority of taonga in the Ngā Pumanawa O Te Arawa exhibition are located in the part of the building assessed at 80% so are safe. We are working with iwi, Te Papa, Auckland Museum and other lenders on a plan for the ongoing care of the few remaining taonga that need relocating,” Mr Brown says.
Council set aside $500,000 this financial year (2017/18) for ongoing work related to the museum.
Elected members received an update on the museum in confidential during yesterday’s [Thursday 6 July] Operations and Monitoring Committee meeting. The update was provided in confidential to enable Council to speak with key stakeholders and museum staff before informing the public.
Upcoming Museum events
During the next two weeks (school holidays) there are free drop-in crafts sessions at Te Rūnanga Tea House. The museum’s education programmes and daily ‘outside the walls’ guided tours will continue and the Rotorua Museum Art Awards will be hosted at the Sir Howard Morrison Performing Arts Centre from 9 September to 6 October 2017.
What’s happened so far
- On 18 November 2016 the museum was closed as a precautionary measure following the appearance of cracks in some parts of the building after the Kaikoura earthquake earlier that week.
- On 2 December 2016, having received a preliminary rapid response report, Council confirmed the building would remain closed until at least April 2017 to enable a Detailed Seismic Assessment (DSA) to be completed.
- Detailed Seismic Assessment (DSA) report was received by Council this week.
- The assessment process took a considerable amount of time. Council set aside $500,000 this financial year (2017/18) for ongoing work related to the museum.
- The museum building is a Category 1 heritage building which is more than 100 years old and was originally a bath house.
- Rotorua Lakes Council undertook earthquake risk assessments of its buildings in 2011 following the introduction of new regulations prompted by the Christchurch earthquakes. Several council buildings were identified as being at risk, including the older, central part of the museum (the bath house) which dates back to 1908.
- As part of council’s earthquake strengthening work programme, engineers were already at the museum in November  to undertake a detailed seismic assessment to further understand the level of risk and develop a plan for strengthening work.
- There was an addition added to the northern end in 2008 and an extension added at the southern end, where the Te Arawa collection is housed, was completed in 2011. These extensions were funded by the Rotorua Museum Centennial Trust which raised $22 million.
- In the 12 months to 31 October 2016 113,450 people visited Rotorua Museum.
- The closure has resulted in an estimated $1.5m in lost revenue (the closure occurred just before the start of the annual busy season).
What did the Detailed Seismic Assessment (DSA) involve?
- The DSA took months to complete due to the complexity of the building, its construction and the various testing that needed to be done.
- The assessment included researching existing documentation and information about the building, opening up and checking the strength of walls (destructive testing), investigating how the building was constructed, core sampling and scans, and geotechnical investigations in the area around the building.
- The assessment was carried out with input from Heritage New Zealand.
What do the cracks look like?

Where are the cracks?
There are cracks throughout the building with most concentrated in the original parts of the building from the foyer to the northern (rose garden) end.
Can you describe the cracks?
There are cracks down walls on the ground floor of the old part of the museum. Some cracks run from the ceiling to the floor and continue along the floor.
Overhead in the basement walkway there have been cracks for many years and a few of these have widened.
Historically, there have always been cracks in the original part of the museum and these have been monitored for any change. New ones appeared after the Kaikoura earthquake.
Are the remaining taonga in the museum safe?
The last few Summers sculptures will be moved out as soon as we can arrange it – due to the weight of these marble pieces, moving them will require special equipment and expertise.
The majority of taonga in the Ngā Pumanawa O Te Arawa exhibition are located in the end of the building assessed at 80% so are safe. Some taonga will need to be relocated and we are working with lenders and specialists on a plan for this.
How many staff have been affected by the closure?
20 staff were affected by the initial closure and were given the option of taking redundancy. Many were placed within other divisions within Council where there were vacancies and others were employed by local tourism operators who offered their assistance.
A core group of staff were retained to continue providing events, education and holiday programmes and other museum services.
How will the cost of fixing the museum be covered?
That will need to be worked out once Council decides how to proceed – that decision will determine what the cost will be.
During 2017/18 Annual Plan consultation Rotorua ratepayers rejected Council’s proposal to introduce a museum targeted rate to cover the revenue shortfall resulting from the closure.
The shortfall will instead be funded through the Uniform Annual General Charge ($14.20 per household).
What about insurance?
Now that we have the detailed assessment insurance is another matter we will need to work through.
Insurance for council-owned assets is very different to, and much more complex than, other types of insurance so it’s not a simple question to answer.
However, even if we were successful in terms of an insurance payout, it’s unlikely that would cover the full cost. Other funding sources will be needed.
