McCullum has played for Rawtenstall in the Lancashire League
Nathan McCullum says he is keen to help the "quality" Lancashire side he has joined in Twenty20 cricket.
The New Zealand all-rounder took 3-31 on his debut as Lancashire's FP t20 clash with Warwickshire at Edgbaston on Sunday was abandoned because of rain.
He told BBC Radio Manchester: "There's a lot of quality in the Lancashire squad, very much so.
"It's very much a decent side and a good bunch of blokes and I'm looking forward to helping them do well."
He added: "I've heard good reports and seen some good results. They're a strong team and I'm just looking forward to getting in there and doing my bit and hopefully we can be successful."
The 29-year-old travels with the second-placed Red Rose county squad to Trent Bridge relishing the prospect of taking on early North Group leaders Nottinghamshire on Tuesday.
"Trent Bridge will be exciting" he said. "I've played there once or twice before and it's obviously a wonderful ground, so it'll be exciting to get back there and have a crack at those guys.
"I guess T20 is not so taxing on the body. It's only 20 overs in the field and things go along pretty fast.
"So it's something you just have to be confident and aggressive about and trust your game."
