Tsunami sirens for Christchurch

4:05 pm on 19 June 2012

Work is underway to install 22 tsunami sirens along the coast in Christchurch.

Contractors will be putting the sirens in place from Waimairi Beach to Sumner over the next three weeks.

Christchurch City Council's civil defence manager Murray Sinclair says the sirens will be tested for the first time on July 22.

Mr Sinclair says the area could be hit by a tsunami triggered by an earthquake far away, possibly in South America or the Pacific Ocean.
