WELLINGTON (Reuters) - Prices for New Zealand's main commodities rose for the fourth month in a row in April, driven by an increase in dairy prices, ANZ Bank's commodity price index showed on Thursday.
The index rose 1 percent for the month, compared with 1.2 percent growth in the previous month.
On an annual basis, the index was 7.1 percent higher, compared with a 5.8 percent rise the month before.
"The main thrust was provided by the dairy complex, while aluminium provided a supporting act as trade tensions and geopolitics boosted prices," said Con Williams, ANZ agri-economist.
Aluminium prices jumped 8 percent on the geopolitical concerns and dairy products, the country's biggest export earner, were up 2.7 percent, as global supply waned.
