have yet vs are yet

Lee’s comments come as the financial hub expects gross domestic product to expand 3% to 5% next year, slower than this year as travel, consumer and construction activities are yet to reach pre-Covid levels. It also follows the government drawing “heavily” on past reserves in its fight to support the economy through the pandemic, Lee said, and running a budget deficit for two consecutive years.

Can "have yet" replace "are yet"? If it is possible, is there a difference in meaning?

Thanks.
