If the inflation rate in New Zealand rises relative to the inflation rate in Australia, this means that the prices of goods and services in New Zealand are increasing at a faster rate than in Australia. As a result, New Zealand consumers may find Australian goods relatively cheaper due to the relative price increase in their local market. Conversely, consumers in Australia may find New Zealand goods more expensive, which can lead to a decrease in demand for those goods.
Therefore, the correct response would be:
Demand for Australian goods will rise.
