Zeta Resources Ltd. plans to make a partial takeover offer to acquire at least 41.955% of all the shares of New Zealand Oil & Gas Ltd., or NZO, for 72 Australian cents per common share.

The company, through its wholly owned subsidiary, Zeta Energy Pte. Ltd., is the largest shareholder of NZO, with a 17.5% stake, and intends to control at least a 50.01% ownership in NZO.

NZO's second largest shareholder, which holds an approximately 8.3% interest, has agreed to accept the offer.

Zeta's independent directors unanimously support the offer, according to the Aug. 10 release.
