Kia ora, good afternoon and welcome to Newshub's live coverage of the New Year's test between the Blackcaps and Australia at the Sydney Cricket Ground (SCG).
The Blackcaps are playing for pride, having lost the first two trans-Tasman tests by 296 and 247 runs respectively, while Australia is looking for a dominant series sweep.
But the Kiwis have lots of work to do after a century to Marnus Labuschagne helped the hosts finish day one on 283/3.
The Blackcaps are fielding an unusual lineup with illness and injury forcing five changes. With Kane Williamson out, Tom Latham is captaining the Kiwis. Jeet Raval, Todd Astle, Will Somerville all recalled, joining debutant Glenn Phillips in the starting side.
Conditions are set to play their part in Sydney, due to the devastating Australian bushfires, with smoke clouding the city.
On top of that, rain is expected on days four and five of the test, which is good news with numerous fires raging around Australia.
