People are still being evacuated from their homes in Piha as land remains dangerous and unstable days after Cyclone Gabrielle.

Locals are warning city sightseers to stay away from the Auckland beach community, saying they are still in the middle of an emergency.

Surf club custodian Paul Newnham says a lot of land is still moving.

"There's still boulders the size of cars falling out of some of these things," he says.

Meanwhile, the second firefighter caught in the Muriwai landslide has died in hospital, Fire and Emergency says.

It takes the death toll in the wake of Cyclone Gabrielle to six.
