Despite a small softening in prices in October and November, global prices have remained firm.
By mid-December, whole milk powder - the most important segment for New Zealand producers - held above US$5000 a tonne.
China's buying has left the rest of the international market with less supply to go round, keeping the market tight, it said.
Rabobank believes many of the buyers in regions including South East Asia, the Middle East and North Africa, have used up all the meaningful back-up stocks after a period of prolonged belt-tightening.
The global dairy market will enter 2014 with farmgate milk prices at record or near record highs in many export and import regions, it said.
Meanwhile the prices of commodity feeds such as soybeans and corn have fallen 10 per cent to 40 per cent below prior year levels in US dollar terms, opening up large margins for milk producers in intensive feeding regions.
Rabobank expects a further increase in China's dairy purchases from the world market in 2014.
``We expect prices to hold around current highs before easing from mid to late 2014 with continuing supply growth in response to significantly improved margins,'' Hunt said.
``Any subsequent reduction in pricing will be limited by structural constraints on suppliers, the need to replenish depleted inventories and ongoing demand growth in line with a slow economic recovery,'' he said.
