It is understood another two houses will be moved on to the combined 1,668sqm site.
"We have real concerns about the impact this is going to have and would really like to block The Block," neighbour Paul Walsh said.
"After the newspaper article last weekend we had an amazing amount of traffic in the street with everyone having a look at the houses - and the show hasn't even started yet."
Walsh said the group had written to Eyeworks, Auckland Council and their local MP voicing their concerns.
Residents said reports of noise throughout the night, heavy traffic, blocked driveways and floodlights during last season's production in Belmont, North Shore, had residents in the usually quiet street worried.
"We've been told of noise complaints every night and the team would down-tools when the noise control officer turned up and start up again when he'd left," Walsh said. "We will not let that happen here."
There were also safety concerns for children at nearby Pt Chevalier Primary School.
"There will be big trucks, builders coming and going and people speeding off. Safety is one of the biggest concerns," Walsh said.
The Block executive producer Greg Heathcote said: "We can give 100 per cent assurance we will follow council regulations. Contestants have to follow the noise restriction rules as part of the game."
