Hi Mar1380,
Welcome to MoveToNZ.
Back at the beginning of the year, there was some bad publicity about Skillsnz. I posted
this warning on the forum, but unfortunately the news site I was linking to doesn't keep its old news items so you won't be able to read what was said. It wasn't good news though. I believe they went bankrupt and left a lot of people out of pocket and without jobs, then they immediately started up a new company. I think they were originally registered as Newjobz when this happened and Skillsnz is the new company name. I hope I've got this the right way round.
If you are looking for a job agent, this forum is linked to a reputable company that handles both jobs and visas. I don't know if you have visited
the site yet.
Edited to add: I just found this on an
Indian forum . Newjobz is the company name before they went bankrupt and started up again as Skillsnz. If you read down the page you will see the name Skillsnz mentioned.
