Bunnings Manager Wins $16,000 Payout: The Legal Battle Over a Withheld Bonus Explained

Author: Lucky Brothers

The recent ruling involving a Bunnings manager highlights a significant case regarding employee rights and the necessity for fair performance evaluation processes. Emily Grinsted, a People and Culture Manager for Bunnings in New Zealand, has been awarded a $16,000 payout after the Employment Relations Authority (ERA) found she was “unjustifiably disadvantaged” by the company’s decision to withhold her performance bonus.

Working with the “Lucky Brothers” team, we have reviewed the details of this legal victory, which serves as a sharp reminder that corporate “coaching” cannot be used as a backdoor to deny contractually implied rewards.

The case of Emily Grinsted v Bunnings Limited [2026] NZERA 236 is a classic example of how a breakdown in communication can lead to a costly legal headache for an employer. Grinsted, who joined Bunnings in March 2025, found herself at the center of a dispute when her performance bonus—part of the company’s annual Short Term Incentive (STI) plan—never arrived.

The Core of the Dispute: “Coaching” vs. “Discipline”

According to the ERA determination released on April 21, 2026, the tension began when Grinsted’s manager, Melbourne-based Rana Obeid, raised concerns about her “communication style” and “fit” within the organization.

• The Company’s Stance: Bunnings argued that Grinsted was not entitled to a bonus because she had not met expectations. They claimed they had raised these issues multiple times as “coaching opportunities.”
• The ERA’s Finding: ERA member Matthew Piper ruled that because Bunnings treated the issues as “coaching” rather than formal disciplinary matters, they had effectively failed to perform the necessary formal assessment to deny the bonus. As per the sources, Bunnings didn’t even tell Grinsted she wasn’t getting a bonus; she only realized it in September 2025 when she didn’t receive the payment or the standard rating letter.

The $16,000 Breakdown

The Authority ordered a total payout of approximately $16,280 (NZD), broken down as follows:

• $11,280 in Bonuses: Calculated as if she had achieved a 75% performance rating for the period.
• $5,000 in Compensation: Awarded for the “injury to her feelings” caused by the unfair treatment and the lack of transparency from the company.

Why This Case Matters for Managers and Staff

This ruling is a massive wake-up call for HR departments and managers across Australia and New Zealand.

1. Transparency is Non-Negotiable: You cannot silently withhold a bonus. According to the ERA, a fair and reasonable employer must engage with an employee regarding their rating, especially if it leads to a financial loss.
2. Formal vs. Informal: If an employer wants to deny a reward based on performance, they must move beyond informal “coaching” and follow a documented, formal performance review cycle.
3. Good Faith Obligations: The ruling emphasized that Bunnings breached its duty of good faith by not allowing Grinsted to respond to the rating that ultimately cost her the bonus.

Final Thoughts from Lucky Brothers

In our opinion, this case proves that even at high levels of management, employees need to stand up for their contractual rights. It’s a “shock and surprise” to see a major retailer like Bunnings skip basic HR protocols, especially when dealing with an HR manager! The lesson here is clear: if you are told you are being “coached,” it shouldn’t mean you are being “canceled” from the bonus pool without a fair hearing.
