Disinfecting water storage tanks
The information on the document below will help you disinfect water storage tanks if you suspect that some water contamination has occurred. The recommended disinfectant is plain (not scented), liquid (not gel) bleach which should have 5% Sodium Hypochlorite written on the label somewhere.
Janola, one of the most well-known bleach brands, shouldn't be used. Manufacturer Pental Products states all Janola liquid bleaches contain surfactants and aren't suitable for treating drinking water tanks. Read more below.

Changes to Pacific Tsunami Warning Centre messages
13 October 2014
The Pacific Tsunami Warning Centre (PTWC) provides information on all earthquakes in the Pacific to national tsunami warning centres (in New Zealand this is the Ministry of Civil Defence & Emergency Management). From today the PTWC will be issuing new, enhanced tsunami messages to the warning centres. It is important to note that in the event of a tsunami threat, advice of this will come from the Ministry of Civil Defence & Emergency Management.
John Hamilton, Director of Civil Defence & Emergency Management, said the Ministry also wished to remind the public that an official warning was only possible for distant (more than three hours warning time) and regional source (one to three hours warning time) tsunamis. “For a tsunami generated very close to New Zealand there simply won’t be time for an official warning,” he said. “It is therefore important to prepare before a tsunami and be able to recognise the natural warning signs so you can act quickly.”
