He said the next international dairy auction coming up soon would be keenly followed.
"There's still a long way to go. Some farmers did do cost cuttings that could come back to bite them but they had to do it at that time to make their budgets work.
"A lot of farmers are sitting on the fence and at the end of this month or the start of December is when they'll sit down and assess their position."
Mr Cullen said the recent rain in light of a forecast dry summer would lift the mood of dairy farmers.
Northland Rural Support Trust co-ordinator, Julie Jonker, said any rise in dairy payout would definitely be a shot in the arm for farmers and the region as a whole, financially and psychologically.
"It's still not a great payout but it's a lot better than what it was. All their [dairy farmers] plans and effort hopefully is going to come to something," she said.
Mrs Jonker said it was good to see farming stakeholders taking to each other and working together despite going through difficult times lately.
New Zealand Chambers of Commerce Northland chief executive, Tony Collins, said the increased payout was welcomed news and would hopefully retain a sense of confidence in the wider business community.
"The latest forecast also shows that Fonterra has identified issues around market and their structure and taken action which is pleasing."
Fonterra chairman John Wilson said that the company's performance between August 1 and October 31 was built on the strong second half of the 2015 financial year.
"While it is tough on farm due to low global milk prices, farmers will welcome the ongoing improvement in Fonterra's performance delivering increased returns," he said.
