He said that following the outbreak the DHB had worked closely with the Ministry of Health to identify the impacts on its normal operating activities and its future plans to invest in equipment and facilities.
"The outcome of those discussions is the additional $1m to support Hawke's Bay DHB to ensure it does not fall behind due to circumstances which were beyond its control."
The DHB initially requested the funding support in about March this year but the ministry declined, saying that instead it would forgive the DHB $1m in its target surplus, which was reduced from $4.5m to $3.5m.
At the time DHB chief executive Kevin Snee expressed disappointment and surmised it was a judgment call on requests of such nature put to it by any of the country's DHBs, which would be weighed up in terms of priority.
Yesterday, a Ministry spokesperson said the reversal of this earlier decision was a common sense approach following constructive talks between the Ministry and the DHB about the impact the outbreak had, and putting a number on it.
DHB acting chief executive Sharon Mason said paying for the gastro outbreak had dented the investment fund the district health board used to provide for new equipment like CT scanners and new buildings like the Mental Health Unit, operating theatres and the gastroenterology build underway.
"The confirmation of financial support will mean the district health board can increase its surplus in 2017-18 by $1m, restoring that fund to match future planned investments such as redesigning and rehousing cancer services and expanding the district health board's surgical capacity."
The inquiry into the outbreak, which the Government established in September last year to investigate the outbreak, its wider causes and the lessons to be learned is expected to be complete by the end of this year.
In June, the Hastings District and Hawke's Bay Regional councils confirmed they would set up the fund to help support those people who had been impacted financially through serious long-term illness lasting for longer than six months, related to the outbreak.
The two councils had each contributed $100,000 to the fund, applications for which close on September 22.
A Hastings District Council spokesperson said they did not know at this point how many people had applied because the applications were being placed in a sealed box behind reception, which would not be opened until after the closing date.
This was part of the process in place to ensure the details of applicants were protected.
Community Health Assistance Fund forms are available on the Hastings District Council website and from the Hastings council office and libraries.
Applicants need to supply a doctor's referral confirming the relationship between their long-term illness and suffering campylobacter as a result of last year's Havelock North water contamination.
The health assistance takes the form of one-off payments with applications assessed by an independent medical professional and a panel making the final decision.
