Civil Defence will be boosted in Little River and Birdlings Flat after residents living near the sea had nowhere to evacuate to after the 7.8 magnitude earthquake on November 14.
Because Birdlings Flat does not have any community facilities, residents had nowhere to stay while they were evacuated from their homes when a tsunami warning was in place following the earthquake.
Nearby Little River was out of the tsunami area, so it did not have any facilities open.
The city council is looking at building Civil Defence volunteers in those areas.
Banks Peninsula Community Board chairwoman Christine Wilson is pleased to see action being taken.
“Around in the smaller bays a lot of residents were evacuated so there needs to be a plan in place and somewhere for them to go,” Ms Wilson said.
“In Lyttelton, we work with Civil Defence so they need that scenario across the peninsula as well so there needs to be further clarity.”
