Kane Richardson has been ruled out of the final Chappell-Hadlee ODI against New Zealand with back soreness, and Western Australian quick Joel Paris will be parachuted into the team.
Richardson was a late withdrawal from Saturday's second ODI, replaced before the toss by Victorian Scott Boland.
An update from Cricket Australia this morning said Richardson continued to suffer back pain and would return to Australia today "for further investigation into the issue".

Australia tied the Chappell-Hadlee series at 1-1 with a four-wicket win in Wellington on Saturday. The third and final match will be played in Hamilton tomorrow, Monday being a public holiday in New Zealand for the nation's Waitangi Day celebrations.
Paris had been with WA's Sheffield Shield squad in Lincoln, where he took 4-37 in the second innings with the red ball as NSW held on for a draw.
Paris made his ODI debut at the WACA in this summer's VB ODI series against India, and also played the second game in Brisbane.

Wicketless in eight overs in his debut match, he claimed the scalp of India opener Shikhar Dhawan in Brisbane with his second delivery.
Paris was also the bowler who delivered a bouncer that jagged back off the Bert Sutcliffe Oval surface catching Ed Cowan on the helmet. The NSW opener was felled by the blow but quickly recovered, but was ruled out of the match under CA's concussion guidelines.

For Richardson, he faces an anxious wait to determine the extent of his back injury with Australia set to announce their World T20 squad later this week.
Richardson was diagnosed with a back 'hot spot' while playing for Australia A in 2013. In 2014, he was also sidelined during an ODI tri-series in Zimbabwe.
"I've always had things like this as a kid and it's one of those things if the physio gives you the all clear you go for it," Richardson said at the time.
The South Australian quick's injury trouble adds another headache for selectors already grappling with injuries to T20 skipper Aaron Finch and pivotal allrounder James Faulkner, who both have hamstring issues.
Boland, Richardson's replacement in Wellington, was despactched for six back over his head from his first ball. His second delivery, however, removed the off bail from Brendon McCullum's stumps.
He finished with 2-61 from his ten overs, his best return of his fledgling international career that has so far yielded 3-320 at 106.66 in five matches.
Victorian quick James Pattinson is now also with the squad in New Zealand, having been withdrawn early from the Commonwealth Bank Bushrangers Sheffield Shield game against Tasmania at the MCG, and indicated his willingness to play an ODI. But that option has been ruled out by CA, with Pattinson instructed to focus on red-ball bowling and the first Test against New Zealand in Wellington starting February 12.
