Wellington Zoo has become the first zoo in 20 years to successfully breed Goliath bird-eating tarantulas.
It is also the first time the "beautiful" spiders have ever been bred in Australasia, said the zoo's team leader of reptiles and invertebrates, Dave Laux.
The massive spiders, which can have a leg span up to 30cm - about the size of a dinner plate - are the largest species of arachnid in the world.
"When we drop to level 2 our doors will be reopening, we will have some new babies for our visitors," he said.
