Australian shares inched ahead on Thursday as higher oil prices lifted the energy sector, while the New Zealand market touched a new peak after a surprise cut in domestic interest rates.

The S&P/ASX 200 index (xjo) added 2 points to 5,159.5. The benchmark bounced almost 1 percent on Wednesday but stopped short of tough resistance around the week's peak of 5,182.5, which had been the highest reading since early January.

The S&P/ASX 200 Energy (GIC) Index .AXEJ rose 1.6 percent after two sessions of losses. Woodside Petroleum Ltd (WPL), Oil Search Ltd (OSH) and Santos Ltd (STO) all made ground.

The mood globally was cautious as markets wait to see what the European Central Bank does at its policy meeting later on Thursday.

Some sort of easing is widely expected, but investors are reluctant to wager on aggressive stimulus given the central bank disappointed so badly back in December.

Perhaps aiming to pre-empt the ECB, New Zealand's central bank cut its cash rate a quarter of a point to an all-time low of 2.25 percent.

Citing a worrying fall in inflation expectations, the Reserve Bank of New Zealand (RBNZ) also indicated that further cuts might be necessary in the months ahead.

New Zealand's benchmark S&P/NZX 50 index (nz50) reacted by rising 0.5 percent to 6,491, having touched a record high at 6,506. The drop in rates made stocks paying dividends look more attractive.

"I think the market is very much driven by the surprise rate cut, the currency coming off, yield players in and also any currency players," said Brad Gordon, investment advisor at Macquarie Equities.

Yield stocks such as Spark (SPK) gained, with the telecoms provider up 1.25 percent.

Fisher and Paykel Healthcare (FPH), whose offshore sales benefit from a lower New Zealand currency, rose 1.1 percent.

Dual-listed ANZ Bank (ANZ) rose 2.85 percent as the bank announced it was considering making two offers of unsecured bonds.
