Australian batsman Darren Lehmann scotched speculation he would retire after his hometown Test match against New Zealand starting Friday in Adelaide.

Lehmann conceded he was under pressure to retain his spot in the powerful Australian side following a run of recent low scores.

The left hander's Test average has plummeted by almost five runs following paltry returns in his past four Tests, but Lehmann said he was not planning to retire after the second Test against the Kiwis at the Adelaide Oval, as suggested by some media outlets.

"I heard that," Lehmann, 34, said of the retirement rumour.

"But I'm definitely not retiring.

"If I'm enjoying cricket, I'll keep playing and I am certainly enjoying playing cricket these days.

"There are no thoughts about that (retirement) at all."

Lehmann's grip on his place became more tenuous following a first Test failure against the Kiwis in Brisbane when he made just eight.

The continued sterling form of New South Welshman Simon Katich, who was overlooked for the Brisbane series opener against the Kiwis as Lehmann returned from injury, has also increased pressure on the South Australian.

Lehmann said he would approach the second Test against New Zealand as if it was his last.
