Nearly five years after a New Zealand bride was killed by a speeding boat in Fiji, a coroner had delivered findings on her death.

Blenheim's Rebecca Stockwell, nee Crawley, 27, was honeymooning with Hayden Stockwell and the pair were snorkelling at a resort in 2007, when she was struck by the speeding six-metre aluminium dinghy.

On Friday, coroner Christopher Devonport delivered his findings on Mrs Stockwell's death.

He looked into her death because her body was brought back to New Zealand, but he cannot make any recommendations to anyone in Fiji.

However, he did comment that his investigation showed Fijian authorities had taken the death "very seriously".

Fiji's labour ministry investigated and ruled that boating channels should be marked by the resort and guests told to keep clear of the channel.

Boating rules for those driving the boats have been enforced, along with first aid training for resort staff, and smaller engines have replaced larger ones.

Matamanoa Island Resort had since been bought by a five-star diving operation, which was actively monitored by Fijian safety authorities, Mr Devonport said.

The boat's driver, Tomasi Tuvou, was found guilty of manslaughter and sentenced to a year in prison, suspended for two years.
