Matt Armitage, who lives about 8km away from the fire, said helicopters were going back and forth to fight the fire.
"They got on top of it pretty quick, but because it is so dry it is still spreading," he said.
"There is a sea breeze coming through which is the last thing we need."
The fire located northeast of the city started just before 3pm and brings no respite for firefighters who have been tackling a large fire in Pigeon Valley near Nelson since Tuesday.
Canterbury Civil Defence and Emergency Management (CDEM) group duty officer Gavin Treadgold said as of this afternoon, it had sent an additional 22 response team volunteers to provide support to the fire response.
"The response we've seen from the community, emergency services and the CDEM efforts so far is outstanding," he said.
"We hope sending additional resource will help further strengthen the already great job they're doing."
It is expected the deployment will last through the weekend.
The Walters Bluff fire comes after the call was made earlier this afternnon to start evacuating the 3000 residents of Wakefield as a result of the Pigeon Valley fire which started on Tuesday.
The Wakefield evacuations affect between 800-900 homes and is expected to take 4-6 hours.
Civil Defence recovery manager Richard Kirkby said residents need to go now. There is no time to dampen down their properties, he said.
Kirkby said between the State Highway and the river, the whole area is being evacuated "as we speak".
"The rest of Wakefield will follow suit, they have all been told to move out, but they are focusing on that first stage and then they will be moving on to the second stage."
Kirkby was encouraging residents to go and stay with family and friends.
"We have opened up the Saxton Stadium and that is sufficiently big that if people need to have a place to stay that will be set aside for them to go and stay there."
Residents are packing their prized belongings and some extra clothing and fleeing.
Nigel Patterson, a volunteer fireman, was watering his brother's house roof before they left.
Next door, a family was packing six cats and a rabbit into a car and driving 16kms away to grandparents.
