Wellington Zoo community engagement manager Amy Hughes saidValentine's Day allows the zoo to be more "risque", with talks on the romantic exploits of popular animals.
"It's a chance for the grown-ups to enjoy a picnic and a glass of wine, and learn more about what goes on when the lights go off in the animal kingdom."
The zoo will stay open from 5pm through to 8.30pm.
"While the event is mostly about fun, it also gives us the opportunity to share stories about the conservation breeding programmes at the zoo, especially for endangered species."
A limited number of close encounters will also be available for those who want to treat their loved one to a wild night out.
"Our close encounters give people the opportunity to get even closer to our amazing animals, while supporting our conservation fund to save animals in the wild."
