Police are continuing to investigate hack on a Christchurch-based cryptocurrency exchange, but their High Tech Crime Group has wrapped up their involvement.
Cryptopia faced "significant losses" after it was hacked in January in what the firm called a "security breach".
High Tech Crime Group staff remain at Cryptopia finishing up aspects of their work but the main part is complete, Detective Inspector Greg Murton says.
"Cryptopia management have full access to their facility and business premises and the police investigation is not preventing their business from getting up and running again."
However, only Cryptopia management can speak to when it may open again, Det Insp Murton says.
The full police investigation is ongoing here in New Zealand and abroad, with New Zealand police working in collaboration with the FBI and international experts.
No timeframe has been given as to when the investigation may finish.
Cryptopia was founded more than three years ago by Rob (Hex) Dawson and Adam Clark.
It allows users to trade a range of cryptocurrencies including Bitcoin, Litecoin and Doge. It has 1.4 million users.
Cryptocurrency news site Coindesk reported at the time that the hack resulted in the loss of 19,391 Ethereum (ETH) tokens worth $2.44 million and 48 million Centrality (CENNZ) tokens worth $1.18 million.
The missing tokens were all reportedly transferred from Cryptopia to unknown wallets.
