Sharemarket investors are unhappy at the "significant effect" that the announcement to phase out TECT cheques has had on the value of Trustpower shares.
New Zealand Shareholders Association CEO Michael Midgley said the share price had shown no signs of recovery.
"In our view this was an entirely predictable outcome," he said in a letter to TECT chairman Bill Holland.
Midgley was commenting on the Tauranga Energy Consumer Trust's proposal to wind up the current trust and transfer its assets into the Tauranga Energy Charitable Trust so that all income was distributed to community organisations. TECT's assets largely comprised a 26 per cent holding in Trustpower.
"The trust's action has been to the detriment of other shareholders as well as the current and future beneficiaries of the TECT shareholding," Midgley said.
