She said she had a lot of faith in the safety and security in London.
Former Rotorua Daily Post journalist Bridie Witton agreed.
"When these things happen it really does make you think twice before you head to an airport or get in the tube but at the same time everyone mainly minds their own business and life continues as normal."
She had seen a heavy police presence on her way home from work, especially in all the tube and rail stations.
Witton, who grew up in Reporoa, said attacks like today's probably worried her family more than her, but she was about to activate a "tag" on Facebook to show people she was safe.
She said colleagues had been in shock about the attack - and initially thought it was a joke.
Former Rotorua man Chris West said he didn't think the attack would change his life in London.
"I already try to keep aware of my surroundings as much as practically possible. However, you can't let fear run your life, it's just one of many risks we face every day."
Mr West said he was saddened following the attack, and felt sorry for the individuals and the family of those who were affected.
"At the same time it was expected that something like this was going to happen in London again at some point."
Meanwhile, Rotorua Daily Post journalist Ruth Dacey's twin brother Matthew was due in Westminster shortly after the attack took place.
He had been walking but got on the tube early, when the tube stopped because of a "serious incident" at Westminster.
"Immediately I knew it was a terrorist attack. I thought the worst because of how everyone is feeling in London at the moment. Everyone is on high alert. "
Once the tube got moving they stopped at Westminster to pick up people, but nobody was allowed off.
"People got on the tube, everyone looked terrified and worried and people were saying they had heard gun shots. I realised because we were still moving it was just an over ground attack."
Mr Dacey said it was not surprising it had happened.
"I just think thank God police and security are so alert because it could have been so much worse.
"It doesn't make me want to move. Attacks like this want to create fear - we need to stand together."
