What Are AI Agents?
AI agents are software systems powered by large language models (LLMs) that can autonomously perform complex tasks. Unlike traditional automation that follows rigid rules, AI agents can:
Reason
Understand context and make logical decisions
Plan
Break complex goals into actionable steps
Learn
Adapt based on feedback and outcomes
Act
Execute tasks using available tools and APIs
Think of an AI agent as a capable assistant that you can give a goal to, and it will figure out how to accomplish it—researching, making decisions, and taking actions along the way.
How AI Agents Work
AI agents operate through a loop of perception, reasoning, and action:
Receive Goal
The agent receives a high-level goal: "Research competitors and create a comparison report"
Plan Approach
The agent breaks this into steps: identify competitors, gather data, analyse strengths/weaknesses, format report
Execute with Tools
The agent uses available tools: web search, document reading, data extraction, spreadsheet creation
Evaluate & Iterate
The agent checks its work, adjusts approach if needed, and continues until the goal is achieved
This is fundamentally different from traditional automation, where every step must be explicitly programmed. Agents can handle ambiguity and novel situations.
Types of AI Agents
AI agents come in various forms, each suited to different use cases:
Task-Specific Agents
Focused on a single type of task like research, writing, or data analysis.
Conversational Agents
Engage in dialogue to help users accomplish goals through conversation.
Workflow Agents
Orchestrate complex multi-step processes across systems.
Multi-Agent Systems
Multiple specialised agents working together, each handling their domain.

Agents vs Traditional Automation
Understanding when to use agents vs traditional workflow automation:
| Aspect | Traditional Automation | AI Agents |
|---|---|---|
| Task type | Structured, predictable | Unstructured, variable |
| Decision making | Rule-based (if/then) | Reasoning-based (contextual) |
| Error handling | Pre-programmed exceptions | Adaptive problem-solving |
| Setup effort | Lower for simple tasks | Higher initial investment |
| Maintenance | Update rules manually | Learns and adapts |
| Best for | High-volume, consistent processes | Complex, judgment-based tasks |

Getting Started with AI Agents
If you're ready to explore AI agents for your business:
Identify suitable tasks
Look for tasks that require research, synthesis, or multi-step reasoning. Good candidates involve gathering information, making recommendations, or handling varied requests.
Start with human oversight
Begin with agents that assist humans rather than fully autonomous systems. Have people review agent outputs before actions are taken.
Define clear boundaries
Establish what tools and systems the agent can access, what actions it can take, and when it should escalate to humans.
Measure and iterate
Track agent performance, gather feedback, and continuously refine prompts, tools, and guardrails based on real-world results.
Key Considerations
Before deploying AI agents, consider these factors:
Reliability
AI agents can make mistakes or hallucinate. Build in verification steps and human oversight for critical decisions.
Cost
Agent operations involve API calls that have costs. Monitor usage and set appropriate limits.
Security
Agents with tool access can take real actions. Implement proper access controls and audit logging.
Data Privacy
Consider what data agents can access and how it's processed. Ensure compliance with NZ Privacy Act.
Learn moreExplainability
Agents should be able to explain their reasoning. This is important for trust and debugging.
