Americans have been advised to "reconsider travel" to New Zealand by the US Department of State Travel.
Similar to New Zealand's Safe Travel advisory, the US State Department provides information and advice on specific countries, which are assigned one of four 'levels'.
Level 1 (Exercise normal precautions), level 2 (Exercise increased caution), level 3 (Reconsider travel) and level 4 (Do not travel).
New Zealand has been assigned level 3, with the US State Department encouraging people to: "Reconsider travel to New Zealand due to Covid-19-related restrictions".
"The Centers for Disease Control and Prevention (CDC) has determined New Zealand has a high level of Covid-19," read an alert on the department website, stating there are restrictions in place that affect US citizens' entry into New Zealand.
