A Kiwi man is recovering after suffering multiple stab wounds in the London terror attacks.

Oliver Dowling, 32, was stabbed in the face, neck and stomach, his sister Freddy posted on Facebook.

He is now recovering after a four-hour surgery.

"Doctors are very happy with how he's come out the other side. A massive thank to the University of London Hospital for their tireless efforts in helping my brother out!!"

It was earlier reported Dowling was an in induced coma.

Freddy also posted that her brother survived because the attackers missed all his vital organs.

Oliver Dowling's girlfriend Marie Bondeville is also believed to have suffered injuries in the attack. Her status is unknown.

"Marie has been in surgery at another hospital but unfortunately we haven't been able to find out how she is due to not being immediate family," Freddy wrote.

A Ministry of Foreign Affairs and Trade spokeswoman said they were working to confirm the reports.

According to Australian Prime Minister Malcolm Turnbull, there are reports that two Australians were also caught up in the attack.

"At this time we are aware of reports of two Australians who have been directly affected by this attack," Turnbull said.

"This afternoon the Foreign Minister has spoken to the parents of both Australians. One case has been confirmed and the Australian concerned is in hospital. In the other case, we are continuing to make inquiries."

Terror struck at the heart of London today as attackers killed at least seven people in a series of vehicle and knife attacks before police shot them dead.

The assault began when a van veered off the road and barreled into pedestrians on London Bridge.

Three men fled the van with large knives and attacked people at bars and restaurants in nearby Borough Market, police and witnesses said.

At least 48 victims were treated at London hospitals and a number of other patients were treated for less serious injuries.

The violence turned a summery night in an area packed with revelers into a scene of panic and chaos, with officers running through crowded streets screaming for people to flee. Lifeboats on the River Thames helped evacuate the area.

The Metropolitan Police force declared the attacks "terrorist incidents."

Assistant Commissioner Mark Rowley said that while they believe all the attackers were killed, the investigation continued.

"We believe three people were involved, but we still have got some more inquiries to do to be 100 percent confident in that," he said.

As dawn broke over the capital, a large area on the south bank of the River Thames remained cordoned off.

Police told people to avoid the area, leaving tourists and revelers struggling to get home.

Only hours before, bursts of gunfire echoed through the streets - likely from armed police - and at least three blasts rang out as officers performed controlled explosions.

One image taken by a witness showed a man on the ground surrounded by police; he appeared to be wearing a vest with canisters attached to it.

"The suspects were wearing what looked like explosive vests," Rowley said.

"But these were later established to hoaxes."
