Northland dairy farm consultant Tafi Manjala said $6.55 was a good payout but farmers should exercise caution between now until the end of the year when the final milk price would be finalised.
If it stayed at $6.55, he said farmers should be able to spend their earnings on things such as farm infrastructure towards the end of the year.
The recent rain, he said, has given farmers about 20 per cent more silage for winter than in past years.
Northland Chamber of Commerce chief executive Tony Collins said the uplift in forecast milk payment would enable farmers to invest in machinery and equipment— something they have not been able to do in the past three years because of low payouts.
"Dairy farming, together with tourism, are crucial drivers of Northland's economy and when these sectors do well, businesses that sell to them do well," he said.
Fonterra typically announces the final milk payout in September.
Last year's final payout price was $6.52 per kgMS which raked in $586.8m for Northland dairy farmers.
