An international organisation that measures corruption is questioning whether New Zealand is doing enough to stop bribery.
Transparency International monitored 37 countries to see which ones were enforcing laws that prohibit people from bribing officials in other countries.
New Zealand was found to have no prosecutions and no investigations underway, placing it in a category described as no enforcement.
Transparency International New Zealand says it suspects foreign bribery is not being reported to authorities, meaning investigations by the police and Serious Fraud Office are very rare.
It says the Government has failed to ratify the United Nations Convention against Corruption and bribery penalties are not as strong as in other countries.
New Zealand was found to have no prosecutions and no investigations under way.
Transparency International New Zealand director Fiona Tregonning suspects there are New Zealand companies engaging in corrupt practices.
"We know that New Zealand companies do operate overseas in countries that have endemic levels of corruption, so I think that it's quite naive to assume that New Zealand companies and exporters acting in those countries in fact have absolutely no participation in corruption that's taking place there."
Transparency International categorised Australia as a country with moderate enforcement, counting two prosecutions and eight investigations that are underway.
