The Government has imposed travel bans on Russian diplomats expelled from other countries in the wake of the Salisbury nerve agent attack.
"We will be asking our security partners to provide those names to us," Prime Minister Jacinda Ardern said in a joint statement with Deputy Prime Minister and Foreign Affairs Minister Winston Peters.
"Those names will then be placed on a travel ban list to ensure that individuals who have been found to undertake activities incompatible with their diplomatic status in other countries do not enter New Zealand."
Ardern and Peters said New Zealand had clearly registered its deep concern over the Salisbury attack and the inadequate response from Russia to justified questions.
New Zealand's views had been conveyed through media statements and in direct discussions with the Russian Government, both in Wellington and in Moscow.
