Between 200 and 250 millimetres of rain is forecast to fall north of Ūawa, near Tolaga Bay, with high tide just after 9.30pm tonight.
Landslides have already started to hit properties in the Gisborne suburb of Whataupoko.
Food provider Leaderbrands said it was reworking deliveries as it dealt with road closures.
State Highway 2 between Wairoa and Napier has reopened again, with State Highway 5 expected to do the same this afternoon. However, many other roads remain closed.
Leaderbrands chief executive Richard Burke said time was important because their products only lasted for 10 days until they went off.
There could be gaps on shelves if trucks were unable to meet their targets, he said.

Welfare checks in Hamilton
Hamilton City Council said its response teams have been doing welfare checks on people affected by flooding, including in Glenview.
Hamilton Airport received 74.8mm of rain in a 28-hour period, submerging Exeter Street in Glenview.
The council's general manager of infrastructure, Eeva-Liisa Wright, said they were working to determine the extent of flooding in some of the city's residential streets.
She said tapwater was still safe to drink.
Meanwhile, SH1 north of Hamilton will be closed tonight for urgent repairs to potholes caused by persistent rain.
All southbound traffic will have to detour at Ngaruawahia on to the old highway between Gordonton Road and Horotiu from 7pm until 5am on Saturday.
The potholes are in an area of the Waikato Expressway where work was underway.
Traffic went down to just one lane and now that lane has potholes.
A spokesperson for Waka Kotahi said contractors have to close the southbound lane to fill and fix some areas, rather than carry on with temporary patching.
Rain eases in Bay of Plenty
The orange rain warning for the Bay of Plenty has been lifted, but residents are being warned that further weather-related problems are possible over the weekend.
Tauranga City Council said the ground could only soak up so much water and, with more rain forecast, there was an increased risk of surface flooding and landslides.
The council has taken the rare step of closing sports fields this weekend.
However, the Chatham Cup football match will go ahead on the Links Avenue field.
Sunday's Blindzone Demonstration involving trucks and buses, has also been postponed due to the weather forecast.
