Fletcher Building has delivered grim news of a $180 million dollar hit to accounts on two big projects.
Costs for Auckland's International Convention Centre are up another $165 million, and a Wellington car park's tally has risen $15 million.
The company's half-year results are due out next Wednesday.
Jarden's Grant Swanepoel says this is the fourth concerning financial 'surprise' from Fletcher in the last 13 months.
