The mild winter means milk supplies will be flowing later this season.
Federated Farmers North Canterbury president Cameron Henderson, an Oxford dairy farmer, said most farmers in the region were reporting a slow start to calving.
''Early in the season we don't really supply a lot, but we normally like to be supplying milk by the 1st of August, but that certainly won't be happening this year.
''Quite a few farmers are saying it's delayed, so whether it's the weather or cows are less stressed, but it's probably a good thing.''
Henderson said he was supplying milk by July 27 last year, but there was no reason to be concerned at this stage. There was plenty of feed around, conditions were mild and the cows were happy.
