Ben Stokes does not see James Anderson stopping any time soon after the "relentless" England seamer returned to the top of the Test bowling rankings.
Australia captain Pat Cummins had occupied the top spot since February 2019, while Anderson was last at the summit in November 2018.
At the age of 40, he is the oldest bowler to reach the top of the rankings since Clarrie Grimmett in 1936.
Anderson took 7-54 across New Zealand's two innings in England's 267-run win at Bay Oval in Mount Maunganui last week, and captain Stokes says his side are fortunate to have him.
"Albeit him being 40, I just can't see him stopping," Stokes told reporters ahead of the second Test at Basin Reserve in Wellington.
"Every time he turns out there, he's one of the main guys you throw the ball to when you feel like you need a wicket. He's just relentless with everything that he does.
"We're very lucky to have him. Rightfully so he's back at the top. I know sometimes those rankings don't mean much to people, but in our opinion, he has been one of the best, if not the best, for longer than what these rankings say."

Asked if Anderson cracked a smile at the news, Stokes quipped: "No. I don't think he'll be that fussed by it, to be honest - he'll just keep doing his thing."
New Zealand skipper Tim Southee also lavished praise on Anderson.
"He's phenomenal and has been for a long period of time," Southee said. "To have played as many Test matches as he's had is phenomenal on its own.
"He doesn't look like he's slowing down any stage. I've thoroughly enjoyed watching it from afar and any time you play against them it's a great chance to catch up and talk to them. To see a 40-year-old sitting at the top of the charts is pretty impressive."
Anderson made more history with his performance in the first Test, as he and Stuart Broad dethroned Australia greats Glenn McGrath and the late Shane Warne as the pair of team-mates with the most Test wickets between them while playing in the same side.
Broad and Anderson have taken 1,009 Test wickets combined from 133 appearances together – Warne and McGrath reached their total in 104 matches.
Stokes has named an unchanged team for the second Test, which starts on Friday, with New Zealand striving to salvage a draw.
While Broad and Anderson did the damage with the ball, Harry Brook was named player of the match after making 89 and 54, while Joe Root returned to form with a half-century in the second innings.
