One of the light displays he won from the Bay of Plenty Times for first prize was stolen, despite it being nailed to the ground.
"Sadly that prize would have been worth about $500 and it was screwed to a plank, so would have taken two people to lift it."
Mr Spalding estimated the vandals caused more than $600 damage.
It took him about three weeks to sort the decorations from their storage places and put them up all over his property.
Tuesday night was the first night of the 2012 Bay of Plenty Times Christmas Lights Trail, which was when Mr Spalding's home was vandalised.
"I went to bed and all the lights turned off about 10.30pm so it must of happened sometime after 11pm. I left at 4.30am to go to work so at that time of the day it was dark and I didn't notice." Mr Spalding got a phone call from his son on Wednesday afternoon saying the display had been damaged.
A reindeer that lit up with blue lights was ripped from its secure spot on the ground, leaving wires severed and empty spaces in his garden.
While he initially felt like simply taking down all his lights, Mr Spalding had decided not to let the vandals get the better of him.
"I just don't understand why anyone would do this, especially at Christmas time. My little girl is pretty upset but I won't get beaten down this easily."
The vandalism has been reported to police.
