The clinic is now a regular feature in the Bay of Plenty Times Christmas Lights Trail and is overrun with festive lights of all shapes, sizes and cat and dog variations.
A dog cocking its leg to urinate was the most recent addition, Mr Drummond said.
"We used twinkly lights and yellow cellophane for the pee but now you can buy orange lights, and they work well.
"It takes a long time. I kind of dread the thought of it but if you're a little late people say, 'are you doing the lights this year, I'm bringing my grandkids in from out of town to see them'."
Terralie Hardy said her husband, Keith, hated putting up Christmas lights at their Sapphire Drive home each year. But once finished, he loved the satisfaction of a job well done.
The pair, who have two sons and four grandkids, have about five boxes full of lights, but Mrs Hardy often buys new ones. And not even their cavalier King Charles spaniel is immune to the Christmas fever.
The dog has a reindeer coat, complete with Christmas lights, and sits at the front of the house every evening, entertaining the local kids.
"I just love doing it for the kids and for my family," Mrs Hardy added.
This year, her favourites are the reindeer on the front lawn. She said a 3-year-old girl asked if Santa was inside their house.
"She said, 'I've been trying to call him, he must be in there because his reindeer are parked on the lawn'," Mrs Hardy said.
"She came back two or three times to have photos taken with the reindeer," Mrs Hardy said.
"I just love it. This is probably my best year, but I have plans for even bigger and better.
"We're still working on it. It's just a continuous thing but we've got to get it right.
"There's other people too. They say 'it might not be the brightest or the biggest, but it's the best'."
