Some Auckland residents say vibrations from construction work on the Southern Motorway have damaged their homes.
The New Zealand Transport Agency (NZTA) says it's working with homeowners, but that it hasn't broken any rules.
Conifer Grove resident Gayleen Smith says she and her family have been subjected to intense vibrations for the past two years.

"The diggers were going up and down, up and down - the house was shaking like anything. There were things falling off the wall, it got quite scary."
Her house lies adjacent to the motorway, and she says the vibrations have damaged both the outside and the inside of her home.
"We've got cracking on the internal walls; we've also got door frames coming away; the floor's moved."
She says initially, her insurance company said it would cover the damage - but that changed a year later.
"It was not accepted because we're not covered for vibration damage."
She says she's gone to the NZTA but isn't getting any help - and she's not the only one. Another property has cracks in its pool, and down the road at the Boageys' household, they say they've had several cracks in their driveway.
In a statement, the NZTA told Newshub it's talking with property owners in relation to "perceived property damage claims as an alleged result of vibration".
But it says it regularly monitors vibration levels, which it says are below its resource consent conditions.
That's little consolation to Ms Smith, who faces a mammoth repair bill of $500,000. She's worried she'll end up homeless.
"We're your everyday Kiwi family - we struggle just like everybody else does."
The NZTA says it will continue working with affected homeowners, but the rumbling won't stop until work is completed towards the end of 2019.
