The work, and the temporary relocation of the hearse, are still being planned and it is not yet decided when the work will take place or whether the centre will need to close during any of the renovation.
Founded as the Hawke's Bay Museum of Technology in 1979 - initially based in sheds at a vineyard - the centre has been the domain of enthusiastic volunteers, including founding member Donald Tucker and engineer and late 1983-1989 mayor of Napier Dave Prebensen. It has found a more permanent home on its current site leased from the New Zealand Defence Force.
Among the current volunteers are retired marine engineer Ian McPherson and civil engineer Gordon Hart, a former manager with highways managers the NZTA (now Waka Kotahi NZTA).
In 1993 its trust merged with the Hawke's Bay Cultural Trust, and with concerns for its future, the Napier City Council - with popular support in annual plan submissions - has become involved in managing the centre through the upgrading of the building.
It currently has standard opening hours of 9am-3pm Monday, Wednesday, Friday and Saturday, and hosts visits and tours, and such events as birthday parties with a difference.
Among plans is an Art Deco Festival event, which among other things will doff its hat to the role played by the Fullagar after the 1931 Hawke's Bay Earthquake, powering the Tent town at Nelson Park and Tin town, via leads between the sites.
