Adding to the uncertainty were various elections to be held across the eurozone during the first half of the year, including the French presidential election in April, Tuffley said.
In the United States, although household spending remained weak, there were signs of an improvement in the US labour market.
Robust Chinese economic data had also appeased market fears of a global slowdown.
"For now, the global growth outlook is not as weak as the Reserve Bank forecast at the December monetary policy statement," Tuffley said.
Domestically, the recovery was continuing at a gradual pace, he said. Business confidence had eased in light of the uncertainty in offshore markets but that was largely expected.
Economic growth was broadly in line with the Reserve Bank's expectations.
Post-earthquake rebuilding activity was expected to provide a boost later in the year but further quakes in December and January increased the likelihood of a delay, Tuffley said.
"With current inflation pressures subdued, and considerable downside risks to growth, the Reserve Bank has no urgency to increase the official cash rate before December 2012."
