New Zealand wicketkeeper Brendon McCullum was on Tuesday declared fit for the second one-dayer against Australia on February 6 after recovering from a hip injury.
With McCullum back to fitness, his standby Gareth Hopkins will return home on Tuesday.
Team manager Lindsay Crocker said McCullum had responded well to the treatment since picking up the injury during training last week.
"The muscle was a bit stiff after the match in Perth on Sunday, but the medical team is confident that Brendon can participate fully in Friday's second ODI," said Crocker.
"It's the selectors' wish that Gareth returns to New Zealand to play in this week's round of State Twenty20 games on Wednesday and Friday. A decision on whether he returns to cover for Brendon over this heavy schedule after Melbourne will be made on Saturday," Crocker added.
New Zealand lead the five-match series 1-0 after winning the opening one-dayer in Perth.
