Laulala, who turns 29 next month, has been with the Chiefs for the past five years and with the Crusaders prior to that.
He joins fellow All Black props Ofa Tuungafasi, Karl Tu'inukuafe and Alex Hodgman at the Blues.
"My wife and I felt the time was right for us to move closer to our families in Auckland. I went to school in Auckland and our extended families are all there," said Laulala.
All four are to play in the Rugby Championship in Australia, with Laulala granted paternity leave to delay his departure across the Tasman.
