Mr Haywood said the lights had been hammered deep into the ground and it would have required some strength to remove.
Mr Haywood said he'd gone to check on the lights about lunchtime, yesterday, when he noticed a cap to one of the solar lights lying on the ground. He then realised most of the collection was missing with just a few left behind.
"Low is not the word here. We're pensioners.
"We don't do this for our own benefit. We do it for the general public and the hospice," Mr Haywood said.
"If we never bought another Christmas light again, it wouldn't worry me because it's not for my benefit.
"We do it for the children and the families who come every year."
In conjunction with the street's other residents, the couple raise money for the Waipuna Hospice. Mrs Haywood said $1800 was raised for the hospice last year.
Daughter Tracy Haywood was outraged. "They raise money for dying people.
"I think it's absolutely despicable. They have to take that money out of their pension to purchase them."
The couple hoped the unique lights would be recognised and returned. They were going over CCTV footage from neighbours.
