Cannot convert .LAZ data set from NZVD2016 vertical datum to DUN58 local vertical datum.

[colhu258]

I will preface this with the fact I am relatively new to PDAL and Python in general. I am running a PDAL pipeline which is suppose to convert a pointclud in LAZ format from NZVD2016 to DUN58. I originally used example 2 found on the PDAL help page for "filters:reprojection" but have found that the "+init=epsg" syntax is deprecated in the current version of PROJ4. As such I found another query here on GIThub which supposedly solved the issue, linked here "#3231" and attempted to use Hobu's solution to no avail.

this is .json file

{
"pipeline":
[
{
"type": "readers.las",
"filename": "Wingatui_NZVD2016_Filtered.laz"
},
{
"type": "filters.reprojection",
"in_srs": "EPSG:2193",
"out_srs": "EPSG:2193+5761"
},
{
"type": "writers.las",
"filename": "Wingatui_DUN58_Filtered.laz"
}
]
}

and I am running it with the command
pdal pipeline test.json in the anaconda powershell prompt. Any help will be greatly appreciated

set PROJ_DEBUG=3 in your environment and run your pipeline with PROJ_DEBUG=3 pdal pipeline test.json --debug --verbose 7 to see PROJ debug output
