A Tauranga woman thought her husband had broken their computer when he started yelling 'oh no, oh no' when he was checking their Lotto ticket online.

But he'd actually just discovered they'd won five million dollars in last weekend's draw.

The woman said she just yelled back at her husband 'what've you done now?'.

The couple didn't get around to checking their ticket until yesterday and collected their win from the Lotto head office in Auckland today.

They said the first thing on the cards will be a holiday.
