A drunk driver was suffocated between his car door and roof after swerving onto the wrong side of the road to hit a "ferret", evidence given to a coroner says.
Rodney Spiers, 30, died on Waikawa Valley Rd in the early hours of the morning on September 25 last year.
He had left Invercargill earlier that day with his friend David McClelland to go on a fishing trip in the Catlins.
Mr McClelland told Coroner David Crerar that Mr Spiers was drinking rum and cola mixers as they drove and became increasingly angry and aggressive.
The car left the road when Mr Spiers swerved to chase a "ferret", Mr McClelland told the coroner.
