3.10.1.1. Interviews
According to Amaratunga et al. (2002), interviews are deemed to be the best method for data collection in case study. The interviews became the most important sources. Furthermore, the researcher can clarify any unclear answers with experts during the interview (Kumar, 2011). Saunders (2016) noted three ways to conduct interviews, namely, structured; semi-structured or unstructured. For structured interview, the interviewees' responses are limited; hence less richness of the data. For the unstructured interview, the interviewees express freely without restriction; but analysing the data might is more difficult due to the absence of consistencies (Myers, 2013). In the case semi structured interview, valuable information of real experiences, interviewee’s interpretations, and recommendations are expressed freely and in detail. The following
table lists varies interview types (structured, semi-structed and unstructured) that can
be used within the research study. The semi-structured interview was used.

The researcher prepared semi structured interview questions for the interviewees. The questions was sent to the PhD Supervisor team for their feedback. After receiving the PhD supervisor's feedback. The revised questions were sent to main contact in San

Francisco as part of approval process for interviews to take place. Once questions were revised, a list of potential interviewees was sent back to the researcher. No Pilot study group was used in this study.
3.10.1.2. Sampling of Participants and Interviewees
Sampling is required for research since there is limitation to research the entire population (Saunders, 2016). When deciding sampling technique, the researcher must consider time limitations, financial, and accessibility to the resources. Two strategies can be used in sampling: random sampling / probability sampling and non-random sampling / non-probability sampling. In random sampling, the chance of each element being selected from the population is usually equal, while, non-random sampling doesn’t give an equal chance to each element being selected. The sampling in the qualitative research is not significant, whereas a sample is used to represent the study population in a quantitative research (Kumar, 2011).
In qualitative research sample size is not an important as in a statistical research (Kumar, 2011). The researcher should attain an adequate size for data collection. Saunders (2016) recommended non-random minimum sample size which is illustrated in Table 3-9.

Nineteenth invitations where sent out by Deputy Program Manager, Neighborhood Empowerment Network, San Francisco in researcher's behalf on November 9, 2016.

Fourteen individuals (Project Managers and Community Leaders) responded to be interviewed over SKYPE, Google Hangout and Phone.

In the case of Christ Church, 30 invitations were sent via contacts, cold calls, and referrals in Wellington and Christ Church, New Zealand. Only 11 individuals were interviewed over SKPE, Google Hangout and Phone in February and March 2017, and October and November 2017. Those who said no were from Engineering and Architectural companies indicated their work centered on buildings and infrastructure not the community. The four individuals interviewed worked on Central Library reconstruction, Town Hall reconstruction, Community revitalization, and multiple community reconstruction. These individuals offered a wealth of information. One individual provided three hours of interviews over a three consecutive weeks. This individual provided a great deal of information of community engagement within Christchurch and active involvement of government in the process. The researcher is extremely grateful of the information and insights presented through the interviews.
