A reward of $350,000 has been offered to help track down the driver who hit a New Zealand man in the NSW Hunter region a year ago and left him to die on the side of the road.
Ian Pullen, 43, had been volunteering as a firefighter at the start of the Hunter region bushfire season.
The husband and father was found on Carrington St, Glenridding, near Singleton, in the early hours of September 29, 2018.
On Friday, his family and police launch a renewed public plea for information on his death with the NSW government offering the $350,000 reward.
Detective Acting Inspector Steve Benson said Mr Pullen's family in New Zealand deserve answers.
"Ian was here doing a job - he was here to help our Hunter community during times of natural disaster and crisis," he said in a statement.
"Someone in the community knows something, and we're urging them to speak up. We want to provide the Pullen family with closure."
His mother Gill Pullen and brother Guy on Friday spoke to media in Newcastle ahead of the anniversary of his death.
"We never thought the last time we said goodbye would actually be the last," Mrs Pullen said.
"He was in Australia doing what he loved - ready to help others at the drop of a hat.
"All we want is answers, and hopefully we get some soon."
