Yes, ZN police authorities now are still working on that case and hopefully it will solve because a lot of traders suffer on their loss due to that exchange.
I don't know which decentralized exchange now we trusted for, hence, they also have a possibility of scam prone. My question is, what exchange next? HitBTC? as I noticed shitty exchange having scam exit.
There some development on the case as reported. And NZ authorities have given the go signal that the exchange can resume their operations. But it seems Cryptopia remains offline as of this time. And hinting from the report, it seems that NZ has cleared Cryptopia of any internal malpractices to say the least

While the police has just given them back their buildings it does not mean they can just start trading again. It would be quite reckless to just throw the doors open without doing a proper security review of everything. There will be quite a lot of work for them to do on their site to ensure safe trading can occur.
As you can imagine - during the investigation there was no staff working on the site (other than to assist the police) and they had no access to their building - now that they do have access to their building they will have to assess the situation and make changes. The police focuses on the preservation of evidence and finding the perpetrator - but the police don't fix the website or whatever cause the breach.
They will also need to prepare for an exodus. There will be quite a few people that will withdraw their funds from the exchange. Times like this remind that it is important to only keep funds necessary for trading on an exchange.
Decentralized exchanges and exchanges with questionable jurisdictions are more risky. Who are the owners ? Who will investigate ? Who will be held responsible ? At least with a licensed exchange there will be some required standards of care and accountability.
