If you are a New Zealand bankrupt, the only travel restriction from the New Zealand bankruptcy point of view is leaving New Zealand. You cannot leave New Zealand without first obtaining permission from the Official Assignee. This applies regardless of which passport you travel on. If you leave, without permission, this is a criminal offence. In most cases, permission is not difficult to get.
A bankrupt does not need to tell the Official Assignee if they are visiting a country other than New Zealand.
If you have a question please ask.
