There are law firms across the North and South Island, in Auckland, Wellington, Hamilton, Christchurch and more.
Experienced lawyers can specialise in many different legal disciplines, from Family law, to Contract law, and other types of litigation. When looking for legal representation, your best bet is to find a lawyer who you can trust and who specialises in the type of legal issues you are facing.
If you need to go to court for any reason, you'll almost certainly want to find a lawyer to represent you, as a good lawyer will understand the New Zealand Legal system, which can be quite complex.
Your lawyer should always work with your best interests in mind, and you should be able to trust that your lawyer will uphold the attorney-client privilege to keep you information strictly confidential.
