The fortunes of Australia, which in the June quarter was New Zealand's biggest export destination, have ramifications for the local economy.
Last month New Zealand's biggest listed company, Fletcher Building, said Australia's economic downturn had detracted from what had been a strong performance in New Zealand.
ANZ Bank chief economist Cameron Bagrie said it appeared that incoming Prime Minister Tony Abbott was likely to play the fiscal austerity card, which could crimp Australia's economic growth in the short run, but which would be positive in the longer term.
Bank of New Zealand's head of research Stephen Toplis said some changes may arise "at the margin" from Abbott's win.
The coalition's intention to tighten up on government spending could represent a "headwind" for a faltering Australian economy, Toplis said, but would benefit the country in the long run.
"There will be slightly tighter control on the fiscal balances, which means that at the margin the Australian economy will be slightly weaker than it would have otherwise been," he said.
Toplis said the new government was unlikely to bring in reform on a "massive" scale, and that the main issue facing Australia was not politics but the end of several years of growth in the mining sector.
Late yesterday, the New Zealand dollar was at A86.8c - little changed from its Friday close, while the Australian and New Zealand share markets registered minor gains.
