New Zealanders look to have heeded Reserve Bank governor Adrian Orr's advice in August and headed out to spend.
Seasonally adjusted electronic card spending lifted 1.1 per cent in August after falling 0.1 per cent in July. Economists polled by Bloomberg had expected a lift of 0.5 per cent.
Core retail spending, excluding fuel and vehicle purchases, lifted 1.3 per cent after falling 0.4 per cent in July.
The central bank cut rates by 50 basis points to a record low 1.0 per cent on August 7 and Orr called on consumers to spend more and businesses to invest more.
"Consumers look to have heeded the RBNZ's advice to go out and spend, but we remain sceptical as to how long this retail resilience will last," ASB senior economist Mark Smith said.
