The military can be activated to deal with a wide range of domestic emergencies. This can range from prison breakouts to geophysical disasters.
In recent years militaries all over the world have highlighted their roles in disasters to try and justify their outrageous costs. Because when disaster does strike civilian agencies such as Police; the fire service, ambulance; the health system; contractors; trucking and logistics firms; commercial helicopter companies; airlines; supermarket chains; and banks are actually more important (e.g. the Christchurch earthquake) than the military.
What the military can do best is ensure that chaos doesn't break out by backing up police and providing any specialist equipment which works where civilian equipment simply cannot.
In neighbouring island nations our military's relatively small transport and engineering capability is relatively more significant because populations are small and the local population may not have the depth and resilience of a nation of of millions rather than tens or hundreds of thousands. That said the military's only real advantage is short term. In the longer term civilian contractors are better placed to provide cost effective solutions in the Pacific. Indeed in many cases it would be cheaper to provide large contracting companies with response contracts for aid work than to use military resources.
That said there will always be a role for our military in establishing a rapid response, assisting with order, and providing some sense that help is coming.
