Abstract
This survey experiment will study whether presenting a vignette on China’s rising aid presence in the Pacific changes views about aid policy in New Zealand (New Zealand is the second largest aid donor to the Pacific). Attitudes in the following areas will be tested: (a) attitudes on total New Zealand aid volume; (b) the Pacific focus of New Zealand's aid; and (c) the purpose of New Zealand's aid giving.

Experimental Details
Interventions
Intervention(s)
In addition to the control group, one information treatment will be provided to a randomly selected sub-set of participants in the survey experiment.

The treatment group will receive a factually-accurate vignette on China’s rise as an aid donor to the region, in which facts are accompanied by matter of fact commentary.

Primary Outcomes
Primary Outcomes (end points)
There are three main outcomes of interest. These are:
1) Desire for level of New Zealand's aid spending to be changed.
2) What the purpose of New Zealand's aid should be (helping developing countries or advancing New Zealand’s interests).
3) Whether New Zealand's aid to the Pacific should increase as a share of New Zealand's total aid spending.

Experimental Design
Experimental Design
The effect of China’s increased aid presence in the Pacific on New Zealander’s views about aid will be evaluated via an online survey of a nationally representative (on age and gender) sample of the New Zealand population.

Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
Power calculations have been conducted to estimate the sample size required based upon the average effect size and treatment group size of similar studies on this topic (e.g. Hoy, Pryke & Wood (2019)). The minimum detectable effect size on the primary question of interest (Desire for level of aid spending to be changed) is around 8 percentage points (with power 0.8 and alpha 0.05) with a sample size of 600 individuals in each group.
