New Zealand leads China 2-1 in their Davis Cup tennis tie in Auckland, after Artem Sitak and Marcus Daniell battled back from two sets down to win their doubles rubber.
In another rain-interrupted encounter in Auckland, Sitak and Daniell eventually overcame Zhe Li and Ze Zhang 6-7 6-7 7-6 6-3 6-2.
The Asia/Oceania Group One tie will be decided by the reverse singles on Sunday, with New Zealand No.1 Rubin Statham first up against Zhang.
Michael Venus, who won his singles on day one, will face Chinese No.2 Di Wu in the fifth rubber if required.
The first day saw two epic single rubbers at the ASB Tennis Arena.
New Zealand dropped the first match with Statham defeated in five sets by Chinese No.2 Di Wu, who won 2-6 7-6 7-6 2-6 6-3 in just over three and a half hours.
The second match featuring Venus against top 200 ranked Ze Zhang eventually hit the court at 10.10pm, after rain delayed the start of Statham's match by three hours.
Venus also won his contest in five sets, beating the top-200 ranked Chinese 6-1 6-4 3-6 6-7 9-7.
