Flaxmere councillor Henare O'Keefe said the small community of Flaxmere would be "devastated" by the sad news.
"I have not seen anything like this in Flaxmere before. It has certainly taken this community by the throat.
"It's about being there for everybody, letting everyone who is affected know that we are there for them."
He said he didn't want to talk about the specific details of the deaths but described the events as "tragic".
"It will be best for us to unite and close ranks. Flaxmere is very good at doing that - we have very good camaraderie."
He said the deaths could have been caused "by any number of things".
"It's a nationwide issue. A burden shared is a burden halved. Don't bundle it up inside - it's okay to ask for help."
He said Flaxmere College, police, Hawke's Bay District Health Board and councillors, including Flaxmere councillor Jacoby Poulain, met yesterday to discuss the deaths and ways for the community to cope.
Hastings Deputy Mayor Cynthia Bowers, who convened the meeting, said it was important to try to understand how and why the deaths occurred and ensure the community felt supported.
"Henare [O'Keefe], Jacoby [Poulain] and I met with the Ministry of Education after they and we had met with Flaxmere College yesterday, just to understand their role and what support they will give.
"It's obviously a tragedy. It's the first time I've been involved in anything like this and it's important that we offer the staff and students of Flaxmere College all the support we can give."
Attempts to reach the board and staff of Flaxmere College last night were unsuccessful.
