Reasons to exclude a supplier
The reasons an agency may exclude a supplier from participating in a contract opportunity.
- An agency may exclude a supplier from participating in a contract opportunity if there is a good reason for exclusion. Reasons for exclusion include:
- bankruptcy, receivership or liquidation
- making a false declaration
- a serious performance issue in a previous contract
- a conviction for a serious crime or offence
- professional misconduct
- an act or omission that adversely reflects on the commercial integrity of the supplier or offends against the Supplier Code of Conduct
- failing to pay taxes, duties or other levies
- a threat to national security or the confidentiality of sensitive government information
- the supplier is a person or organisation designated as terrorists by New Zealand Police
- human rights violations by the supplier or in the supplier’s supply chain
- any matter that materially diminishes an agency’s trust and confidence in the supplier.
- An agency must not exclude a supplier before it has evidence supporting the reason for the exclusion.
- An agency should notify a supplier of its exclusion and the reasons for it.
Serious performance issue
If serious issues with past performance are identified and there is supporting evidence, you should consider excluding the supplier from participating in the contract opportunity. See the guidance note on Rule 46 Awarding the contract.
If you discover that the same errors appear in responses from different suppliers (eg misspelled words or the same mathematical mistakes), this may indicate that these suppliers have shared information (eg cut and pasted content from each other’s responses) and may be acting anti-competitively.

A conviction for a serious crime or offence includes a conviction for foreign bribery (getting an advantage in an international transaction by offering bribes to foreign officials).
