Rain threatened to ruin any chance of a result in the deciding third Test between New Zealand and South Africa on day five Wednesday in Hamilton.
New Zealand, needing a win to tie the series, have South Africa 80 for five in their second innings and 95 runs short of making New Zealand bat again.
However, the start was delayed with drizzle falling after several hours of torrential rain overnight and further showers forecast throughout the day.
South Africa are 1-0 up in the series after winning the second Test in Wellington by eight wickets.
The first Test was also rained out on day five when evenly poised with South Africa 224 for six in their second innings, a lead of 191.
