Sheep and beef producers were the least optimistic, just 9 per cent expecting conditions to improve and 36 per cent expecting a deterioration.
That fall in confidence reflected the decline in lamb prices from historically high levels, and the state of the economy in key export markets.
Tough trading conditions in Britain and European Union markets, combined with the high dollar, had seen lamb prices drop by about 20 per cent to 25 per cent since the corresponding time last year, he said.
Rabobank's latest agribusiness review showed total sheepmeat and lamb export volumes were 8 per cent stronger year-on-year in June, about 29,600 tonnes.
Exports to Britain were 41 per cent lower in June at 3700 tonnes, while exports to the EU (excluding the UK) were 17 per cent lower at about 6000 tonnes.
Most international dairy commodity prices should show signs of stabilising in United States dollar terms through August, the report said.
In New Zealand, June monthly export data confirmed the shipment of heavy volumes from last season in the winter months: export volumes were 27 per cent higher than the previous year and even 8 per cent higher than May 2012.
That meant the export volume was more aligned with levels seen during the peak months of November and December.
Exports to China also jumped compared with June 2011: shipments in the first half of 2012 were up 10 per cent, China accounting for 22 per cent of total exports in the same period.
The worst US drought for more than 50 years drove global grain prices to record highs during July, and many regions in the US reported declines in milk production during June.
The drought was expected to further reduce milk production growth for the rest of the year.
The ASB New Zealand commodity price index remained largely flat in the week to August 3.
While prices started to lift in US dollar terms, that was offset by the continued strength of the New Zealand dollar.
