Jerry Collins' baby daughter is well enough to leave hospital in France.

The former All Black and his partner Alana Madill were killed in a car crash last month when they were hit by a bus on a French motorway.

Their three-month old daughter Ayla suffered life-threatening injuries and has undergone a number of emergency surgeries.

Last night, Ms Madill's sister Nora revealed the baby was recovering well and would be taken to mother's native Canada, where she'll continue to be treated at a children's hospital.

"Through Alana Madill and Jerry Collins' strength and protection, their sweet bella Ayla Collins has miraculously fought to recover. Ayla still has a long road ahead of her but she no longer requires emergency care in France."

Madhill said Ayla will continue to receive everyone's prayers, love and support in Canada.
