It's unethical to discriminate against your own citizens. They have zero obligation to provide entrance or any service to foreigners. No one has a natural right to enter New Zealand, especially if they aren't providing value to that country. That's one of the sad costs of public safety nets though. You need to control immigration to keep out people who would take advantage of it. Otherwise this wouldn't be an issue.
