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 were enforcing laws that prohibit people from bribing officials in other countries.
New Zealand was found to have no prosecutions and no investigations underway, qualifying it for 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.
