Bruce Pepperell says if anyone had written an exercise scenario that said you were going to have your largest earthquake since 1855, followed by a tsunami, followed by floods, slips and swarms of bees and just about everything else, you would have said: don't be ridiculous.
But he's made a number of recommendations for improvement, the most important of which is teamwork - and warns Wellington needs to be prepared. "We need to be ready for the next fight because it's the next fight that's important, it's not the one you've just finished that defines you."
Bruce Pepperell was appointed manager of the Wellington Region Emergency Management Office, or WREMO, in October 2011.
Civil Defence Emergency Management Group joint committee chair Ray Wallace says,since then, Pepperell has made Wellington better prepared for a natural disaster.
He's seen the organisation go from many staged groups into one united force.
