Why not build the new huts first?

One News reports:

Furore has erupted near the remote, rugged country of Te Urewera, where work is now underway to strip, dismantle and burn down backcountry Department of Conservation huts.

At least 15 are gone and another 33 are set to be removed by December, set to be replaced with a “new kind of visitor experience”.

Hikers and hunters claim they have been dismissed, without any consultation, details or timeframes. …

Exactly what will be built to replace the huts, and when, remains unclear.

A post on a Facebook page run by Ngāi Tūhoe this month suggested new accommodation could be built in “2 to 3 years” but said “things like pandemics, wars and inflation make you shy to commit to timeframes”.

“Your association to these places are acknowledged and respected, but that enjoyment has often come as a cost to others,” it said

Surely the sensible thing to do is build the new huts first and then demolish the old ones?
