The daughter of a man who died during the Francie disaster a year ago wants someone to be held accountable for her dad's death.

Today marks the one-year-anniversary of the fishing boat tragedy on the Kaipara Harbour.

It claimed the life of skipper Bill McNatty and seven customers on board the Francie.

Three other men miraculously survived.

Among the dead was 56-year-old Taulagi Afamasaga, fondly known as "Lagi".

His daughter Amy Yerro says she still can't bring herself to visit the Kaipara Harbour.

"The reason why I haven't gone there is – it will be my final goodbye to my dad. It will be my way of letting him go" she said tearfully.

The Francie sank after trying to cross the notorious bar on the Kaipara Harbour in rough seas.

Afamasaga's body was found 10 days after the tragedy.

"Dad was drifting out at sea for 10 days, then retrieved on a beach. It's not nice to think your loved one was alone, in that condition for all those days."

The Transport Accident Investigation Commission says an investigation into the tragedy is in the analysis phase.

It says a draft report is being written which will be finalised next year.
