Exhibit 99.1

Legal Action Against New Zealand Subsidiaries

James Hardie Industries plc (James Hardie) announced today that the New Zealand Ministry of Education has commenced a ‘representative action’ in the New Zealand High Court against two New Zealand James Hardie subsidiaries (the Companies) and other parties.

The New Zealand Ministry of Education is claiming weathertightness defects in relation to several thousand New Zealand school buildings and is seeking repair costs and unspecified and unquantified damages in relation to the alleged defects.

James Hardie and the Companies are working with legal advisors with respect to their response to the claim. At this stage James Hardie is not able to assess what proportion of the claim relates to the Companies or comment about the validity and/or any potential financial impact of the claim.

James Hardie will make further statements as appropriate.

Background

James Hardie has made previous disclosures relating to New Zealand weathertightness product liability claims in Q2 FY13 and Q3 FY13 (please refer to Note 9 of the Notes to the Consolidated Financial Statements for those quarters) and previously made statements in reference to general liability claims in Q3 FY12, Q4 FY12 and Q1FY13.

In Q3 FY13 the Company made the following disclosure (Note 9 of the Notes to the Consolidated Financial Statements):

Since fiscal year 2002, the Company has been and continues to be joined in a number of product liability claims in New Zealand that relate to residential buildings (single dwellings and apartment complexes) and a small number of non-residential buildings, primarily constructed from 1998 to 2004. The product liability claims often involve multiple parties and allege that losses were incurred due to excessive moisture penetration of the buildings’ structures. The claims typically include allegations of poor building design, inadequate certification of plans, inadequate construction review and compliance certification and deficient work by sub-contractors.

The Company recognises a liability for both asserted and unasserted New Zealand product liability claims in the period in which the loss becomes probable and estimable. The amount of estimated loss is dependent on a number of factors including, without limitation, the specific facts and circumstances unique to each claim brought against the Company, the existence of any co-defendants involved in defending the claim, the solvency of such co-defendants (including the ability of such co-defendants to remain solvent until the related claim is ultimately resolved), the availability of claimant compensation under a Government compensation scheme, the amount of loss estimated to be allocable to the Company in instances that involve co-defendants in defending the claim and the extent to which the Company has access to third-party recoveries to cover a portion of the costs incurred in defending and resolving such actions.

Historically, the Company has been joined to these New Zealand product liability claims as one of several co-defendants, including local government entities responsible for enforcing building codes and practices, resulting in the Company becoming liable for only a portion of each claim. In addition, the Company has had access to third-party recoveries to defray a significant portion of the costs incurred in resolving such claims.

Despite having resolved a number of legacy product liability claims in New Zealand since 2002, the Company is becoming exposed to liability for a greater proportion of these claims due to the insolvency of co-defendants and the expiration of some of the Company’s rights of recovery from third-parties. Accordingly, losses incurred in connection with defending and resolving asserted and unasserted New Zealand product liability claims in the future could have a material adverse effect on the Company’s financial position, liquidity, results of operations and cash flows.
