Bug experts were preparing for a huge influx of insects as the weather became warmer for most of the country.
In January, Kiwis were warned about an almost "biblical plague" of insects as the warmer weather arrived.
"Well, it wasn't a difficult prediction. We knew that the weather had been damp for a while. We had an early spring and a mild winter, so we knew it was coming," Pest Management Association vice president Dr Paul Craddock said The Project.
The treacherous weather in Auckland on Friday caused a bug bonanza to go boom.
"It's unseasonably wet, and warm. And now that it's clearing up, you're getting this recall happening where there's lots of bugs and what have you outside and they're starting to come inside," urban pest controller Owen Stobbart told The Project.
Flies, mosquitos, and cockroaches that just won't budge are everywhere.
"The bugs, mainly insects and spiders, have been displaced by the flooding. And so where their homes have been overrun by water, they're just being more obvious because they're coming inside and going up walls or coming in kitchens," Stobbart said.
New Zealand is facing a changing climate - one that's got critters rubbing their mandibles with glee.
"It's an unusually busy year. We do see it occasionally but yeah, this year's been exceptional," Craddock said
The warmer temperatures have seen the worst kind of creepy crawly emerge in Dunedin, with exterminators like Seth McPhee seeing more spiders in the city than ever before.
"It's really just a density issue. This year's been one of the worst years in the last couple of decades that we've had to deal with for just so many spiders," pest controller Seth McPhee told The Project.
