DIY hunting or hunting without a guide in New Zealand is always an option. The major difference you will find in hunting on public land on your own versus private land with a guide is in the game management or more specifically the lack of game management. On most government land there is no season so animals get hunted all year round by residents and DIY New Zealand hunters which naturally forces them to live in steep and inaccessible areas. These areas will have very low quality of food due but the hunting pressure forces them them.
Helicopter hunting is also very common on government land, this means that at any stage during a hunt on public land helicopters can and will come through your area especially for Tahr & Chamois.
All of the private land that New Zealand Safaris hunts on is managed, helicopters are prohibited and we hold the exclusive hunting rights. The game animals on these properties have a value and are respected. These private properties are huge, averaging between 15,000-40,000 acres of mountain to hill country. Each mature trophy animal that is harvested is paid for (many thousands of dollars) directly to the land owners. This then means that animals are not over shot without value as opposed to government land.
Less hunting pressure, better quality feeding areas, animals get a chance to grow old and big which then creates superior genetics. Hunters with a tight budget and more interested in shooting an animal of any size of sex and where age is not important will be more suited to DIY New Zealand hunting.
