      abstract = {Over the period 1991-2003, New Zealand’s milk production  more than doubled. At the same time, dairy farming expanded  its boundaries into non-traditional dairy production  regions. 
The distribution of regional production is of  particular interest because of effects on supply and demand  balances for key inputs and outputs. Changes in the  geographical distribution of dairy production alter local  economic output and, consequently, income distribution and  community viability. The aim of this paper is to present  regional short-term estimates of demand for selected key  production inputs and milk output. Short-term estimates for  milk production and land use were derived based on past  growth rates in stocking rate, cow numbers and productivity  per cow for each region. Input demand forecasts were, in  turn, derived using regional milk production and land use  forecasts and baseline estimates of input and energy use  reported in Wells (2001). Results indicate that by season  2006/07, the effective area devoted to dairy production  will be at 1.56 million hectares, a 7% increase with  respect to the 2003 baseline. However, contrary to what  happened prior to 2003, almost all the gain in dairy area  is explained by increases in the South Island. Over the  same period, national milk production is expected to  increase by 20% to 1,431 million kgs. MS. Similarly, the  South Island accounted for much of the gain, increasing its  share in total milk production to 34% up from 28% in 2003.  
It is expected that the use of inputs such as nitrogen,  potassium, phosphorous and sulphur per unit of area will  intensify for all dairy regions. However, the increase in  the use of inputs per unit of area relative to the baseline  is lower in long-established dairy regions, Northland,  South Auckland and Taranaki, than in non-traditional dairy  regions like, North and South Canterbury, Otago and  Southland.},
