A fatal jet boat accident was caused by steering failure after a wire broke and a shackle fell off, according to Maritime New Zealand which has alerted boaties to check their steering systems.
Cameron Moore, 45, died after his jet boat crashed into a steep bank of the Clutha River on February 24.
Moore was racing in day two of the Otago Rivers Jet Boat Race when his boat left the water and skidded roughly 20m up the bank.
Maritime NZ were still investigating the tragic crash but said the two D-shackle pins on the tiller arm lock were wired together, which could cause excessive stress on the locking wire.
Deputy director compliance systems delivery Pelin Fantham said Maritime NZ was asking all jet boats owners to check their steering set-ups as soon as possible.
