The washout of the fourth ODI between the Black Caps and Sri Lanka in Nelson on Saturday means the series will be decided at Mount Maunganui's Bay Oval from 11am tomorrow.
The Black Caps lead 2-1 but pitch conditions could play into Sri Lanka's hands, particularly if they bat second.
Former New Zealand swing bowler Chris Pringle says the Bay Oval wicket has traditionally been on the slower side with tennis ball bounce, which will suit Sri Lanka more.
"There is no doubt about that as they like the slower, sub-continent-style pitches," Pringle said. "But the rain around the Tauranga area could have added to the moisture in the pitch which might hold it together a bit better for longer, depending on the drying conditions.
"[Sri Lanka] looked all at sea batting first and did not seem to know what they were doing as far as setting a target was concerned and constantly lost wickets. When they chased on a slower pitch [Nelson] they looked very comfortable and looked like they wanted to do that.
