A third death related to the flooding around Auckland has been confirmed this afternoon.

Police have confirmed that Fire and Emergency workers at a Shore Rd property that had been hit by a landslide found one person deceased earlier today.

Police will now make enquiries on behalf of the Coroner.

Two other deaths have been linked to the flooding - one body was found in a flooded culvert in Wairau Valley on the North Shore last night and another man was found in a nearby carpark this morning.

One person is still missing after being swept away at Onewhero in the Waikato District.

Meanwhile, Monday's Laneway Festival in Auckland has been cancelled.

The cancellation of the music festival - which included artists like Haim and Phoebe Bridgers - follows the cancellation of both of Elton John's Auckland shows this weekend.
