Someone walking past said her neighbour could probably help and went to fetch them. While she was away, Cain said the SPCA told her they could not help as they did not have a means to lift the grate and it would be best to call Christchurch City Council.
However, the neighbours arrived and managed to lift the grate off before scooping the ducklings into their bucket.
"The ducklings were scattering and scared, but we got them all out," Cain said.
"They ran so fast to their mum and then the mum walked away with them towards Hope St."
Ducklings being swept into drains is not a new issue for Christchurch.
In another incident, a family of ducks on Riccarton Rd and Wharenui Rd were rescued from a drain and given back to the mother. But one of them was then unfortunately hit on the road.
SPCA animal ambulance team leader Amber Knipe said it has taken in 55 ducklings since September last year.
Knipe said the SPCA is asked to attend three to four duckling jobs a day during duckling season.
If you spot some ducklings trapped in a street drain, they can sometimes be rescued and returned to the mother if she is still around, Knipe said.
The SPCA can assist where it has the availability to do so. It also has arrangements with other local services like Fire and Emergency NZ.
