Efforts underway to salvage catamaran that ran aground

Efforts are underway to salvage a damaged catamaran that ran aground in Canterbury's Banks Peninsula at the weekend. The Black Cat Cruises vessel got into trouble during a return journey on Akaroa Harbour, prompting the rescue of dozens of people on board. The Transport Accident Investigation Commission has begun an investigation while local authorities try to quell the impact of thousands of litres of spilt diesel on the harbour. Adam Burns reports.
