"Between 90 and 150mm of rain seem to be the common figures," Galloway said.
For areas surrounding Hastings, the amount of rainfall was higher than typically expected, while for those in the foothills of the ranges – Patoka and Tikokino – the rain was badly needed to get them to normal.
The high volume of rain proved too much for some in the horticulture and cropping industries down in the flats, though.
"There's some water lying in some of the paddocks and that will have done some damage to the crops."
With parts of paddocks flooded, and some needing to resow crops, Galloway expected there would be an impact on the yields of some horticulture crops.
Havelock North-based Strawberry Patch owners Ian and Maree Tucker said the rain had caused "a bit of rot" in their crop.
