And time is running out, with the sun and a drop or two of rain during the week having given the growth a nudge, and a mow likely to be needed during the weekend.
Mua said that along with the outpourings of concern were offers of help from people wanting to "bring their mowers down at the weekend" to get the job done.
She said the marae, which was built as a community marae for Napier and opened in 2007, was known for the perfection and care taken with the lawn, edges and garden.
On Thursday, the theft remained a mystery other than that some time between late afternoon Sunday and Tuesday morning someone cut off the locks on the shipping container that housed the equipment.
With fences separating the marae from neighbouring Maraenui Park, it was thought the only way way it could have been taken away was via the exit onto Riverbend Rd, and probably on a trailer.
But anything which has been seen or heard and which might be relevant to the theft is important to make sure the mower can be returned.
"We worked really hard to get the funds to get these items so our marae always looks pristine," she said. "We do not have insurance to cover these items and would appreciate it along with the other items that were taken returned."
