NZX, the stock market operator, said it doesn't know why its share price has declined, in response to a query from its disciplinary arm.
The New Zealand Markets Disciplinary Tribunal special division was alerted on Oct. 17 when shares of NZX fell 8.7 per cent over 20 days to $1.16
from $1.27.
The share price fell further to close at a two-year low of $1.14 on Oct. 20, which is 17 per cent below its June 20 close of $1.38, special division chairman Andrew Beck said in a query to the NZX.
"We are aware of no specific reasons for the price decline," NZX chief financial officer Bevan Miller said in a statement responding to the query.
He said the NZX had complied with listing rules requiring the timely disclosure of material information.
