"The medical team have done a really good job and having that full squad to choose from hasn't probably happened to us for a while so we're very pleased," he said.
Auckland face an arduous start to their ITM Cup campaign with consecutive away games against Hawkes Bay and Canterbury, and Pivac said it was crucial for his side to hit the ground running.
"It's a tricky first 10 days, really, with Hawkes Bay away, who are obviously a very good side, and then defending champions Canterbury on the Wednesday," he said.
"If we can get through those first two weeks it will set ourselves up really well, but if we don't then we'll be chasing the pack, so it's very important that we get a good start."
