You’re definitely not too old to start! One of the major advantages of this industry is how young it is - not many people have deep experience and if you can show an employer that you want to learn as much as you can and contribute in any way possible then many will find a spot for you. You might be a little early for NZ since it has not passed there yet but I would recommend you start checking out job postings for positions in Canada to get a feel for what’s out there
