The euro has taken another tumble, as the market nervously eyes a shift to the far-left in Greece.

Voters have just elected a party which is promising to end years of extreme austerity measures.

ANZ chief economist Cameron Bagrie says [told Mike Hosking] there are worrying rumblings Greece could leave the Eurozone.

"The real issue is the contagion risk. If Greece decides to pack their bags and leave, who's potentially next.

"You've got to think about whether they'll get frozen out of capital markets. They'll want some sort of debt relief."

Meanwhile, an improving US economy and the Euro's instability could benefit New Zealand's exporters.

Both factors have contributed to the New Zealand dollar dropping faster than expected against the US dollar.

ASB economist Jane Turner says that will be good news for exporters focused on the US market.

"The lower New Zealand dollar helps improve the competition, but we're also seeing the improved US economy and improved demand."
