New Zealand evidence on impacts across crops is very limited. Precipitation and temperature changes alone show minor effects on crop yield, and winter yields of some crops may increase  . For temperate fruit, loss of winter chill may reduce yields in some regions and trigger impacts across supply chains  . Increased pathogens could damage the cut flower, guava and feijoa fruit growing and the honey and related industries . The combined effects of changes in seasonality, temperature, precipitation, water availability and extremes, such as drought, have the potential to escalate impacts, but understanding of these effects is limited.
