Otago left armer Neil Wagner has been called into the New Zealand squad cover for the injured Tim Southee.
The New Zealand spearhead has an irritated disc in his back, which necessitated a hospital scan last night.
He bowled five overs on the second day of the opening test against Australia at the Gabba today before walking gingerly off the field.
Wagner, a regular member of the New Zealand squad, will join the group when it reaches Perth, venue for the second test starting next Friday.
"Tim will continue to be monitored and assessed over the coming days, but it's important we have all of our bases covered," coach Mike Hesson said.
