Police confirmed that one person had since died following a crash near Te Haroto on Sunday.
The crash occurred on SH5 at the intersection with McVicar Rd near Te Haroto at 4pm. Five people were taken to hospital following the crash.
Two people are now in a stable condition, one is in a serious condition and one has been discharged.
Inquiries into the circumstances of the crash are ongoing.
The death has taken the toll in Hawke's Bay this year to nine, all in the wider Napier-Hastings area and, despite the emptying of the roads in the Covid-19 lockdown, one more than at the same stage in 2019, and the highest January-June figure for the region in the past three years.
