If you currently have a third level .nz name such as kiwiblog.co.nz please be aware that if you have preferential rights to that name at the second level (ie kiwiblog.nz) then you ONLY have until 1 pm on Monday 30 March to register or reserve that name with your preferential rights.
After 1 pm, ANYONE can register your name at the second level, if you have preferential rights to it and do not exercise them.
I have registered kiwiblog.nz, but if I had not then ANYONE else could register it after 1 pm on Monday 30 March.
If you wish to check the status of any names you have, go to anyname.nz. Just enter in your current names and it will tell you whether or not you have preferential rights to the second level version. If you do, you can then either reserve that second level name free of charge for two years at that site – or you can register it for use through your registrar.
But again you only have until 1 pm on Monday the 30th to reserve or register it with preferential rights. After that time it is first in and first served.
