The Conservation Care Department maintains, and if possible, improves the condition of the collections so they can be usefully studied, exhibited and interpreted.
Preventive conservation focuses on controlling the four major threats to object stability - the environment (temperature, humidity, light), pests, handling and transportation.
Regular monitoring of the environment is carried out using electronic data loggers. Large fluctuations in temperature and humidity are avoided to prevent expansion and contraction of organic materials and the abrasion, cracking and fracture that may result. Light exposure is limited to prevent fading and embrittlement of more fragile organic materials such as textiles, artworks on paper and archival documents.
Pest management is always a challenge in a climate where insects flourish and the range of collection materials offers a full and varied menu. Non-toxic methods of pest control like freezing are used in preference to chemical fumigation. Mould prevention is critical with Auckland's reliable high rainfall, requiring close humidity control and the use of buffering materials in microclimates such as display cases and storage boxes.
Conservation staff are also responsible for the packing and transportation of collection items. Requirements vary from individual objects through to entire exhibitions.
The focus of treatment is the Museum's own collection objects, these vary from architectural structures as large as a Māori wharenui (meeting house) to objects as small as a hummingbird's egg. Treatment priorities are guided by Collection Management priorities and exhibition requirements.
