Alterhouse Launch Cashback Promotion — Terms and Conditions
Promoter: DNG Construction Ltd (trading as Alterhouse), Unit 3, 89 Vickerys Road,
Wigram, Christchurch 8042 ("Alterhouse", "we", "us").
1. Promotional period and enquiry
1.1 A "Qualifying Enquiry" is a client's first contact with Alterhouse about a specific proposed
renovation or build project, whether by phone call, email, Alterhouse's "Find out if your
renovation or build qualifies" enquiry form, or any other means Alterhouse accepts, made
during the period beginning 9:00am NZST on 1 October 2026 and ending 11:59pm NZDT on
31 January 2027 (the "Promotional Period")..
1.2 To be eligible for this promotion, a client must make a Qualifying Enquiry about the
project during the Promotional Period. There is no deadline under these Terms and
Conditions by which the resulting Qualifying Contract (see clause 5) must be entered into —
but no cashback is payable unless and until a Qualifying Contract is entered into and
reaches practical completion in accordance with clause 6.
2. Eligibility
2.1 This promotion is available where the project (not merely the client) has not, as at the
start of the Promotional Period, already been the subject of an executed building or
renovation contract, or an accepted quote, with DNG Construction Ltd or Alterhouse. A client
who has previously contracted with DNG Construction Ltd or Alterhouse for a different,
separate project remains eligible in respect of a new project.
2.2 The project must be located within the Canterbury region. Alterhouse may, in its sole
discretion, consider a project outside this area, or decline a project within it, on a case-by-
case basis.
2.3 This promotion does not apply to:
(a) earthquake, natural disaster, or insurance-funded repair or reinstatement work (including
EQC-related work);
(b) projects requiring resolution of council enforcement action before work can commence;
(c) heritage-listed buildings requiring Heritage New Zealand Pouhere Taonga approval; and
(d) any other project type Alterhouse notifies as excluded prior to that client's enquiry.
2.4 Making a Qualifying Enquiry does not guarantee that Alterhouse will accept the project,
and creates no obligation on either party. All projects remain subject to Alterhouse's normal
consultation, feasibility, design and pricing process, and Alterhouse may decline to proceed
with any project in its sole discretion.
2.5 The client entering into the Qualifying Contract must be 18 years or older and have full
legal capacity to contract.
2.6 This promotion is not open to employees, contractors, or immediate family members of
DNG Construction Ltd, Alterhouse, or any person materially involved in administering this
promotion (including George Design).
3. No chance element
This promotion does not involve any draw, ballot, or other random or chance-based selection
process. Every client who makes a Qualifying Enquiry during the Promotional Period, and
subsequently enters into a Qualifying Contract in accordance with these Terms and
Conditions, is entitled to the cashback described in clause 6.
4. Privacy, marketing and publicity
4.1 By submitting the enquiry form, the client consents to Alterhouse collecting and using
their information to assess their enquiry and contact them about their renovation or build
project, in accordance with Alterhouse's privacy policy.
4.2 Separately, and optionally, the client may consent to receive ongoing marketing
communications from Alterhouse. This is not a condition of entering the promotion.
4.3 As a standard part of this promotion, the client agrees that Alterhouse may photograph,
film and otherwise use their project (including during construction) for Alterhouse's own
marketing and social media purposes. Alterhouse will act reasonably in doing so, and a
client's request not to feature a particular aspect of their project does not affect their
entitlement to the cashback under clause 6.
4.4 Entry to this promotion requires the client to tick:
☐ I confirm I have read and accept the Terms and Conditions of this promotion.
and, separately and optionally:
☐ I consent to receive ongoing marketing from Alterhouse.
5. Qualifying Contract and minimum value
5.1 To qualify, the client must have made a Qualifying Enquiry about the project during the
Promotional Period, and must enter into Alterhouse's standard building/renovation contract
for the construction phase of that project (the "Qualifying Contract"), with a contract value
of at least $30,000 including GST by 31 December 2027.
5.2 Where a project involves a separate design, consenting or pre-construction services
agreement in addition to a construction contract, only the construction contract is the
Qualifying Contract for the purposes of this promotion. Entering into a design-only
agreement does not, on its own, qualify a client for any cashback.
5.3 The cashback amount is determined by the table below, applied to the final Qualifying
Contract value (including GST), including any approved variations, as at practical
completion.
Qualifying Contract value (including GST) Cashback (GST-inclusive)
$30,000 - $99,999 $2,500
$100,000 – $149,999 $5,000
$150,000 – $199,999 $10,000
$200,000 – $249,999 $15,000
$250,000 – $299,999 $20,000
$300,000 and over $25,000
5.4 Only one cashback applies per project/property, regardless of the number of contracts,
clients, or owners associated with that project.
6. Payment of cashback
6.1 The cashback is only payable once the Qualifying Contract has proceeded to practical
completion, and the client has met all payment obligations under the Qualifying Contract as
they fall due.
6.2 By default, the cashback is paid to the client as a cash payment following practical
completion. A client may instead elect, before practical completion, to have the cashback
credited against their final invoice under the Qualifying Contract.
6.3 No cashback is payable, and no entitlement accrues, if the client cancels or terminates
the Qualifying Contract, or the project otherwise does not proceed to practical completion,
for any reason.
6.4 The cashback cannot be transferred, exchanged, or applied to another client's project.
6.5 Alterhouse is not liable for any delay to practical completion, or any resulting delay to
payment of the cashback, caused by events beyond its reasonable control.
6.6 Any tax obligations (including GST or income tax) arising from a client's receipt of the
cashback are the client's responsibility. Alterhouse recommends clients obtain their own tax
advice.
7. Cannot be combined
This promotion cannot be combined with any other Alterhouse promotion, discount, or
separately negotiated commercial arrangement, unless Alterhouse agrees otherwise in
writing.
8. Fraud, misrepresentation and clawback
Alterhouse may disqualify a client from this promotion, and may reclaim any cashback
already paid, if it reasonably considers the client has misrepresented their eligibility, acted
fraudulently, or structured a project artificially (for example, by splitting what is genuinely a
single project into multiple contracts) in order to obtain or increase a cashback entitlement.
9. Liability
To the maximum extent permitted by law, Alterhouse is not liable for any loss or damage
(including consequential loss) arising from a client's participation in this promotion, except to
the extent caused by Alterhouse's negligence or as required by the Consumer Guarantees
Act 1993 or the Fair Trading Act 1986. This clause does not limit Alterhouse's obligations
under the Qualifying Contract itself.
10. Relationship with the Qualifying Contract
These Terms and Conditions govern this promotion only. They do not form part of, vary, or
otherwise affect the terms of the Qualifying Contract. If there is any conflict between these
Terms and Conditions and the Qualifying Contract, the Qualifying Contract prevails, except
in relation to the client's entitlement to the cashback itself.
11. Changes to this promotion
Alterhouse may vary or withdraw this promotion at any time, but only in respect of Qualifying
Enquiries made after the date of that variation or withdrawal. No variation or withdrawal
affects the entitlement of any client who has already made a Qualifying Enquiry in reliance
on these Terms and Conditions, provided that client goes on to enter into a Qualifying
Contract for the same project.
