I would say you need to fix this problem first - it may be the cause
of your troubles.  Have you installed the PPA so that you are getting
the v33-fixes version, rather than the original v33 in the standard
packages?  When doing a big upgrade (between versions or changing to
the PPA) I have on occasion had the mythbackend package not install
until some of the other new MythTV packages were installed.  Running
"apt update && apt full-upgrade && apt autoremove" a second time fixed
this.  Note the "full-upgrade" option.

There are two sorts of EIT EPG data, transmitted as separate streams.
The first is now/next data - it is only for the current programme and
the next programme.  It seems like that is the data you are getting,
and I always thought that MythTV did not get that data.  The other EIT
stream is full data for a week, which is the one you want.

For New Zealand, I do not recommend just using the over-the-air EIT
data, as there is information in it in non-standard formats (such as
series and episode numbers) that really should be processed to convert
it to the proper xmltv format before it is read by MythTV.  The way
you do that is to grab the EIT or MHEG5 EPG data using an external
program, then process that data using the xlmtv-proc-nz program. There
are install instructions on list archives for doing this with
mhegepgsnoop, including the workaround for using HDHR tuners.  But it
is not all in one intelligible post.  So if you need or want to try
this, you should probably ask here for proper instructions.
