New Zealand came out on top in terms of ease of starting a business, fixed telephone tariffs and redundancy costs. Low tariff barriers, a lack of bribery and corruption and government subsidies were listed as other strengths.
In the sub-categories the country came 59th for direct overseas investment, 56th for exchange rates and 56th for fixed broadband tariffs. It also scored poorly for the current account balance and mobile phone costs.
IMD said the biggest challenges facing New Zealand this year would be continuing to recover from the Canterbury earthquake, building a nationwide broadband network "to underpin growth", and strengthening the economy's productivity performance.
Returning to a budget surplus by 2014/15 and building better public services through restructuring in high spending sectors were other challenges.
IMD ranks countries according to four main categories - economic performance, government efficiency, business efficiency, and infrastructure.
New Zealand's highest ranking was in government efficiency (10th) and lowest was in economic performance (40th).
The United States regained the top spot and the top European nations were Switzerland (2), Sweden (4) and Germany (9). Others in the group which had lost significant ground since 1997 included Argentina, Brazil, France, South Africa and Britain.
