The Hawke's Bay region is calling out for more Government assistance following Cyclone Gabrielle.

A report has found the area will have ongoing economic losses of $3.5 billion dollars over the next 10 years if no support arrives immediately.

Rockit Apples chair John Loughlin says they'd like $750 million dollars to help with clean ups and replanting efforts.

He says if they don't get help, the results could be disastrous.

Loughlin says it will cause downsizing and jobs losses, similar to when the Whakatu freezing works closed.
