Stock market operator NZX has suspended trading in shares in listed financier Cynotech Holdings.
Cynotech's annual report for the year to March has still not been filed, despite being due on 2 August.
Shares in Cynotech trade on the stock exchange's alternative NZAX board, and have lost more than 25% of their value this year. They last traded at 2.5 cents.
Cynotech Holdings told investors last month that it was considering de-listing from the NZX, but its shares would be listed on an alternative exchange.
