The triplets' parents, Jane and Martin Weekes, had been in Qatar for the past five years. They returned to Wellington to give birth to the triplets after they were conceived using IVF.
According to TVNZ, Jane won a 'Best Mum in Doha' competition for her effort raising the triplets. She had commented: "A mother's love is not divided amongst her children, but multiplied by each child."
On her profile page on the parenting website BabyCenter.com, Jane said she was at her happiest when her children sat around "laughing like loons at each other".
