"So take this in the context of what the presentation is. I don't want anybody not sleeping tonight."
Mr Hazlewood ran through potential hazards to Hamilton including river erosion, interruption of the bulk water supply, incidents involving trains carrying dangerous material through the tunnel that runs under the CBD, industrial accidents and flooding.
The latter has been exemplified recently as a result of successive subtropical cyclones.
"We're not talking about a minor few inches any more on some of your roads," Mr Hazlewood said.
"We're talking about major flash flood issues, as well as those affected by increases of water in the river."
He pointed out earthquakes as a real threat.
"When we talk about what the risks are to Hamilton, the reality is Kaikoura is 530km from here, and Kaikoura resulted in the Raglan water supply being shut down," Mr Hazlewood said.
"In fact for one of my colleagues behind me, it resulted in more than a third of the water leaving his swimming pool because the water was sloshed out. That's something 530km away.
"If you put that more in perspective of what we've got just outside of Hamilton, your nearest fault line is only 40km away, so if you think about what Kaikoura did to this region, think about what one of those closer earthquake lines would do."
The team also detailed existing planning for Civil Defence emergencies, and the ongoing construction of a new Civil Defence operations centre in Hamilton City - which is to be complete with a septic tank, multiple IT lines, phone lines, back-up power, seismic strengthening, and located on Bryce Street.
"Genesis Energy is a lifeline partner of the project," Mr Hazlewood said.
CitySafe and the transport operations centre will also work closely with Civil Defence to ensure the optimum performance of their operations.
The team collectively said although it hopes no severe events happen that affect Hamilton, they ensure their operation will be fully prepared to provide support in any kind of disaster.
