A Christchurch family is considering selling their home because of the neighbour's noisy spa.
Burnside resident Sharyl Teh says the heating unit in the spa switches on at random times, day and night, making noise and causing the whole house to vibrate as if there was heavy machinery constantly doing work outside.
Teh says she has filed noise complaints and even sought legal advice.
The Christchurch woman says her husband tried reasoning with the neighbours but she told Fairfax that "obviously didn't work".
"The broken nights sleep isn't funny anymore," she added.
