Former Australian star Mark Waugh has suggested limited overs captain Aaron Finch's time could be up.

Finch has struggled majorly for form in the last 24 months, having not scored just a single half century in his last 12 ODIs.

He has started the summer with scores of 15, 1 and 5 against Zimbabwe, and added just another five in the first ODI against New Zealand on Tuesday in Cairns.

Dismissed LBW, Waugh summed up the wicket after Finch closed the face of his bat to a straight one and attempted to play into the leg side.

"He just can't access the ball. When you lock yourself in like that, it's a good bit of bowling, no doubt about it, but you have to be expecting that if you're a right-hand batsman," Waugh said on Fox Cricket during the match.

Waugh said that the selectors may have to make a "tough" call on Finch if his form continues.

"The selectors have shown a lot of faith in him, they have given him a lot of lee-way as well," Waugh added.

"At some stage, if he keeps failing in this series, I think the call has got to be made sooner rather than later.

"I know it's tough, but he can't last forever. Everyone has a use by date. He can't last forever."

"There are two more games to go in this series - he might come out and bat really well.

"The selectors will be hoping like hell he does that, because this could easily impact his T20 World Cup coming up as well."

Finch is unlikely to be dropped mid-series as captain, or before the T20 World Cup, however, that tournament could prove to be his swansong from the international arena with another 12 months until the 2023 ODI World Cup, to be held in India.
